Creativity

Across a range of research on creativity a number of recurrent themes can be identified, and the concern here is with two such central issues concerning music performance and creativity. The first, implicit in the focus of this article, is the understanding of creativity as a collaborative, emergent social process. While few scholars nowadays would deny that creative work needs to be conceived of, at least at some level, as social, there is still a considerable and lingering attachment to the idea of creativity as inherently individual. Clarke has commented on a similar perspective in (largely cognitive) research into the nature of performance creativity, which has tended to model improvised performance as an internally produced set of algorithms without full acknowledgement of the inherently social nature of improvised performance.Footnote ¹⁰ The individualized conception of creativity seems particularly enduring within much Western music scholarship, its fundamental warrant being the notion of the single authorial voice.

The critique of the autonomous individual creator lying outside the sociocultural narrative is not new. Much sociological and psychological work stresses the systemic nature of being novel. The work of Howard Becker, which adopts a symbolic interactionist viewpoint, has examined a number of different art worlds, including jazz, in an attempt to lay bare any romantic assumptions of the lone genius.Footnote ¹¹ Meanwhile the work of Mihalyi Csikszentmihalyi, from a systems perspective, views the process of creativity as involving the individual creator, the knowledge domain from which the work develops, and the socioeconomic field in which the work is assessed; but while Csikszentmihalyi acknowledges the way that the ‘social’ presupposes and defines any creative act, he still views that act as decidedly individualist at the level of production.Footnote ¹² A number of research strands have since helped to shift the notion of creativity in various fields of performance, including jazz, away from this individual-centred perspective: these include work on the distributed nature of knowledge and cognition in team work,Footnote ¹³ ethnographic studies of creative musical interaction,Footnote ¹⁴ and recent studies that emphasize creativity as ordered through emergent, complex, and collaborative elements.Footnote ¹⁵

But beyond their focus on individual production in performance, there is a second significant way in which the systemic perspectives are inadequate, and that is their concomitant tendency to view creativity as an extraordinary capacity outside of everyday competence. There is a real danger, as Clarke has pointed out, that too broad a notion of creativity lacks explanatory power.Footnote ¹⁶ At the same time, however, if there is too radical a distinction between the everyday and the out-of-the-ordinary practice of creativity, we lose sight of the constant dialectic through which creativity arises: that between routine or mundane practices and innovation within a cultural field. The sociolinguist Michael Silverstein has theorized this dialectic between immediate performance and wider sociocultural conditions in his work on indexical order and metapragmatics in speech,Footnote ¹⁷ work that has been influential in recent studies of jazz interaction.Footnote ¹⁸ In a similar way, I wish to explore the manner in which musicians engage in the mundane making of an ending within a cultural context informed by an ideology of inventiveness. There are thus two potentially conflicting constraints on how to end a tune: on the one hand the weight of a radically inventive musical tradition and, on the other, a more conservative burden – the moral imperative towards good conduct in the moment that allows all concerned to come out of the risky business of performing with some dignity.

Knowledge

What sort of things do musicians need to know in the act of creating? Although the form of improvisation associated with jazz is usually seen in terms of players exercising their autonomy, improvisation more accurately occurs through degrees of heteronomyFootnote ¹⁹ – the ways in which knowledge and musicians' interventions constrain, regulate, and indeed liberate one another.

Without attempting here a review of the social nature of knowledge, it might be useful to set out some of the pertinent perspectives on how and what musicians know in order to improvise. Lucy Green has identified a spectrum of learning that operates in popular music, and her distinction between ‘conscious’ and ‘unconscious’ approaches to learning emerges from a wealth of research in psychological studies that distinguish between tacit and explicit forms of knowledge.Footnote ²⁰ Both are heavily at work in the context of a jam session. In the present case study, just before the band begins the tune ‘Sunny’, the guitar player takes the bass player through the chord changes, simultaneously playing the chords and naming them, thus laying out the bare minimum of harmonic knowledge that the bassist will need. This awareness of chord sequences is part of the conservatory or self-directed training that musicians need to have mastered prior to any serious work on the jazz scene. The way in which musicians gain knowledge of chord changes or types of ending will differ from one individual to another, and has varied historically. Access has been more regulated and consistent since the widespread dissemination of Real Books in the early 1970s.Footnote ²¹ On the one hand this cultural shift towards learning from texts rather than recordings has made a more extensive pool of tunes (with broadly correct harmonizations) available to musicians. At the same time it has led to a certain ossification of the repertoire: material that is left out of Real Books is much more likely to be ignored. And while such texts have allowed accurate harmonic knowledge of the repertoire to become more widespread, they do not necessarily solve the problem of congruence between players. As pianist SC remarks: ‘The only problem is, different people learn different versions of tunes; I find that sometimes you turn up to a jam and you get somebody playing some sort of weird substitutions which they've learnt from a different Real Book, or something.’Footnote ²² SC also comments on the way in which jam sessions seem, in his recent experience, to have become more restricted in terms of repertory:

Implicit in the above comment is the perceived need to develop a library of tunes within one's memory.

In Do You Know…? Robert Faulkner and Howard Becker explore the world of jazz repertories, highlighting the way in which a repertory is not just a knowledge base but becomes the fundamental focus for making one's way in the world of jazz.Footnote ²⁴ One can see this clearly at work in the context of the jam sessions examined in this study. The house band for the jam tended to choose a repertory centred on the compositions of the iconic players in jazz, in contrast to the jam proper, during which the majority of tunes tended to be staple fare from the American Songbook.Footnote ²⁵ The workings of musical knowledge, however, are evident not only in such representational schemata as chord symbols and musical formulas: musicians also possess le sens pratique.Footnote ²⁶ A comment from pianist HA exemplifies this: ‘In terms of how to end [a tune], usually I follow a little bit first because I don't think I can push them into any direction. I think they can do it more than I can. If I try too hard, it won't sound good […] so I will tend to follow what is happening.’Footnote ²⁷ Here we have an illustration of tacit knowledge (albeit knowledge that can be reflected upon after the event), in which one of the musicians describes his understanding of how he contributes to the organization of the ending by sensing whether it is appropriate to lead or follow at that point. His role as pianist in part determines his understanding of how to proceed, but knowing ‘what to do’ also includes both the aesthetics of shaping an ending and his sense of his position and status as a player within the hierarchy of the scene.

While there will be considerable overlap between the knowledge of ending forms used by a rehearsed group and a group of jammers, the critical difference lies in the degree of pre-planning that occurs. The jam session effectively frames the collaborative creativity: since it is understood by the players that heavily scripted endings will not work in this environment, the prevailing creative aesthetic tends to permit a degree of latitude and free play. When an ending is not planned in advance, jazz musicians rely on a stock of cultural models whose basic types are made up of a further set of structural, temporal, and harmonic features. GB, a saxophonist, commented on the variability and viability of such models as he made the distinction between endings for show tunes (which make up the bulk of the standards repertoire) and numbers written by jazz musicians.Footnote ²⁸ In the former category it is much more usual to revert to one of the stock endings, which in his words ‘just allows the band to tread water’, whereas in the latter category it is more likely that the tune will possess a quite specific ending that one would be expected to know. He felt that to play a ‘tag’ or other stock ending on a jazz number (he gave Joe Henderson's ‘Inner Urge’, and Wayne Shorter's ‘Speak No Evil’ and ‘Witch Hunt’ as examples) ‘would kind of be inappropriate […] it would sound alien’.Footnote ²⁹ So, in the minds of players, different parts of the repertory may be associated with different degrees of scripting as the song is brought to an end.

Over the fourteen numbers played in the jam session in question, there was a clear division between these two types of ending: in show tunes or standards from the American Songbook the use of a ‘tag’ – the repetition, usually a number of times, of a single melodic phrase (and its underlying chord progression) or an extended improvisation based on the tune's final bars – and in jazz or blues numbers the use of simply the composed ending or cadence of the tune (or ‘head’) on its final return. Five out of six jazz numbers at the session and the three blues numbers were concluded within the head itself, whereas the numbers from the American Songbook all finished with an extended tag that merged into closure with a marked ritardando. The type of ending adopted is therefore not simply a matter of performance practicality but a question of preserving the generic identity of the piece.

A working knowledge of musical materials, however, is insufficient; also important is the way in which that knowledge is distributed and applied within the group. This is not simply a question of the sort of distributed cognition that Edwin Hutchins has examined:Footnote ³⁰ rather, it includes reflexive awareness on the part of participants about this distribution. Musicians need not only to know the ‘what’ of performance, but also to be sensitive to the character of the event, which will shape the application of their knowledge on any particular occasion. The subtleties of their knowing ‘what to do when’ do not constitute information that can be gleaned from formal study. Saxophonist GB, for instance, described how his knowledge of leading a group was something developed tacitly over time:

This last comment leads into the second factor that enables musicians to collaborate in creating an ending – their conduct on the ‘stand’.Footnote ³²

Conduct

I would like to begin by situating conduct in relation to interactive behaviours in performance. The aim here is to deploy methodologies concerned with interaction to provide an empirical basis for looking at conduct, a term that tends to be associated more with macro- than with micro-social studies.

Studies of creative interaction have made a significant contribution to our understanding of the ways in which creative processes are constituted in complex systems far removed from the autonomous art-object perspective. Such studies tend to apply descriptive methodologies to real-world performance. Across this spectrum of research lie ethnographic studies of jazz interaction, fine-grained studies of gestural and attentional behaviours,Footnote ³³ and investigations of the emergent dynamics of musical entrainment amongst musicians.Footnote ³⁴ This sort of research goes some way towards remedying a key lacuna that Keith Sawyer and Stacy DeZutter have identified in much work on creativity: the failure to analyse the detail of group interaction.Footnote ³⁵ Both their study and Sawyer's work more generally point towards new openings in the study of creativity. Proposing the term ‘collaborative emergence’ to describe situations in which the group work concerned is unpredictable in terms of outcome, Sawyer and DeZutter have used interaction analysis methodology to present a detailed dissection of an improvisational theatre performance. This form of analysis is a relatively recent interdisciplinary approach that has emerged from sociolinguistics,Footnote ³⁶ and has its roots further back in the work of social phenomenologists such as Alfred Schutz and George Herbert Mead.Footnote ³⁷

Two areas of interest to interaction researchers have been the use of gaze and gesture to coordinate the flow of utterances in face-to-face interaction. Research into gaze has been directed towards the ways it offers an index of accessibility and commitment to any ongoing interactions. Adam Kendon has systematically analysed the function of directed gaze in terms of the way in which it monitors – and thus also becomes a means of regulating – the behaviour of others.Footnote ³⁸ The other significant area of research into non-verbal communication has focused on the use of gesture in encounters. A number of taxonomies of speech gesture (drawn notably from the work of David McNeill, and of Paul Ekman and Wallace Friesen) have been influential in the analysis of music performance.Footnote ³⁹ Within ethnographically based studies of communication in performance,Footnote ⁴⁰ and psychosocial research on gestural communication in music,Footnote ⁴¹ the impact and meaning of bodily movement have been researched using classifications derived from the study of gesture in speech. In this study I borrow from interaction analysis methodologies (that is, the measuring of gaze patterns, body positioning, and gesturing with the musical instrument itself), but confine my analysis of communicative sound and bodily gestures to those that are directly involved in the creative management of the performance. So, unlike many studies of gesture and performance, mine is not concerned with communication that is overtly directed outwards to the audience, though it is fully recognized that the intercourse between players is unavoidably transmitted to the audience at some level. Rather my focus is on the way in which such interactive behaviours form a pattern of conduct, and it is by way of the notion of conduct that I relate the mundane creation evident in these jam sessions to the sense of jazz performance as part of a broader creative ideology.

Conduct emphasizes the moral imperative for musicians to pool their resources and collaboratively shape the performance. The intersubjective accomplishment of action in a jazz performance may be unpredictable, but there is no doubting the commitment to collective action. This does not mean that power and hegemony are not features of performance, but it does mean that there is an underlying communicative rationality (in the Habermasian sense) that prefigures conflict and contest.Footnote ⁴² Forms of conduct become apparent in the momentary interactions of players, but emerge fundamentally from the constraints of the creative field in which they work. Conduct is used here also in a second and more clearly musical sense: the way in which musicians might organize and guide one another in their work. These two senses of the term are not mutually exclusive: the organization and management of others through the use of signs, sonic and visual, is intimately linked to the notion of conduct as an overarching way of being.

The theorization of social conduct has been explored as a site of regulation, training, and instrumental rationality. For Foucault, as a philosopher of power, the development of conduct occurs through various techniques of training and repetitive practice,Footnote ⁴³ and for Bourdieu, practice or conduct within a field is closely allied to the securing of status and power, as reflected in his work on cultural capital.Footnote ⁴⁴ Such rather pessimistic approaches to social conduct have been applied to the field of jazz, where the securing of prestige and power is understood as part of the struggle of working as a jazz musician.Footnote ⁴⁵ But while there may well be elements of the strategic and the instrumentally rational in musicians’ dealings with one another, there are surely less abject dimensions to their creative practice. Mark Banks has pointed to Alasdair MacIntyre's work on social virtue as a more benign account of practice within a community (though MacIntyre is not fully optimistic about the scope for virtue in contemporary society). MacIntyre argues that practices such as jazz generate ‘goods’ that are both internal to the carrying out of the practice (in other words, they are obtainable solely and exclusively through its exercise) and external (in that they may be obtainable through that same practice but are equally obtainable through other practices). Some of the internal goods that Banks has identified within the practice of jazz include the creative fulfilment involved in performing and the feeling of community that jazz practice engenders; an external good, on the other hand, might be receiving payment, a common benefit of jazz performance but one that might equally be gained through any number of other occupations or practices.Footnote ⁴⁶

How musicians behave towards one another has a direct bearing on the outcome of the performance, as can be seen from the following analysis in which musical conduct, rather than knowledge alone, is the key to the band's ability to finish a song (more or less) together. In the following section I explore the jammed ending of ‘Sunny’ in some detail, and look at the ways in which musicians know about what they are doing and how they conduct themselves in the course of the creative process.

Creating an ending in a jam session

Within jazz practice the jam session has traditionally functioned as a place of musical development, social support, and career opportunity for musicians.Footnote ⁴⁷ As a performance mode it currently occupies a space somewhere between a formal public performance and the private, after-hours music-making of consociates, but its roots, certainly at the birth of bebop, suggest a much more private affair – ‘an uncorrupted, unmediated, and uncommercial form of musical expression’ – in which musicians sought escape from the pressures of the paid gig or concert stage.Footnote ⁴⁸ On the London scene jam sessions have developed into a hybrid kind of performance – one that is attended by audiences (that frequently pay) but whose incorporation of players from the floor, informality of presentation, lack of preparation, and paucity of payment place it at some distance from the concert or club date.Footnote ⁴⁹

The significance of jamming in the development of jazz reflects the nature of a music that demands interaction and a deft response to the momentary negotiations occurring in performance – hence a musical sensitivity that cannot be developed purely through the solipsistic routines of private practice. The jam session also allows for the invigoration of musical scenes through the coming together of players of different levels of experience and capacity, providing less experienced players with an opportunity to engage with their seniors.Footnote ⁵⁰ The benefits of legitimate peripheral participation, however, work both ways: the inclusion of younger players can also provide older musicians with new stimuli and refreshing encounters with new ideas communicated with vigour.Footnote ⁵¹ As inexperienced players are inducted into the scene, the scene is disturbed, compromised, and challenged through different ways of playing, and more experienced players have to learn how to accommodate newcomers.

The venue for this jam session was The Spice of Life, a pub in Soho in the West End of London, which hosts a fortnightly Sunday afternoon session organized by Tomorrow's Warriors.Footnote ⁵² The pub is a long-established music venue and holds regular jazz gigs. The jam sessions attracted a mixed audience of between twenty and thirty people, made up of not only musicians wanting to take part but also listeners taking the opportunity to hear Sunday lunchtime jazz at a modest price (entry was £3). The format of the session followed the common model of a house band playing for about one hour, with the jam then being opened to musicians from the ‘floor’. The session was ended by the return of the house band for a final set.

The performance whose ending is analysed here involved four musicians – a guitarist, a double bassist, a pianist, and a drummer. These players were of different levels of experience and status. The bassist is a well-known figure, who has enjoyed considerable success with a number of groups over the years; the guitarist, though an amateur musician, has been playing for a long time and is experienced as a ‘gigging’ performer. The pianist and the drummer, on the other hand, are both young players at the start of their careers: the pianist is a rather exceptional young musician who has been attending jams over a number of years, while the drummer came to the sessions as part of the Tomorrow's Warriors young musicians’ project.

‘Sunny’ – analysis of an ending

A rather unremarkable tune, ‘Sunny’, is the basis for this analysis. It began its life as a pop song, written and performed by the late Bobby Hebb, a minor pop star working in the 1960s. The chord progression is given in Example 1 in its usual key of A minor. The song carries none of the weight associated in the jazz canon with the tunes of John Coltrane, Wayne Shorter, or Joe Henderson, but it has featured in the repertoires of many performers, including Nancy Wilson, Gene Harris, George Benson, Oscar Peterson, and Pat Martino.

In the moments before the performance of ‘Sunny’, there was some limited discussion. First, as mentioned earlier, the guitarist went through the chord sequence of the song with the bassist; this is standard practice among jazz musicians, and at that point it would be expected that the player in question would have the ‘roadmap’ secure in his head. The pianist and the guitarist then discussed who would play the head of the tune, and it was agreed that the pianist would play the ‘in-head’ and the guitarist the ‘out-head’.Footnote ⁵³ Agreement was then reached on the tempo proposed by the guitarist, and finally the rhythmic feel of the piece was established: ‘straight eighths’ rather than ‘swung’.Footnote ⁵⁴ The way in which they would end the piece was not discussed. In the case of a reasonably well-known standard there is the tacit understanding that one of a relatively small number of endings will be used, but the decision concerning which one tends to be made in the moment.Footnote ⁵⁵ As will become clear in the analysis, the route through to the end of the song was not without incident in this performance, and the ending was not as clean or coherent as the players might have wished. It must be stressed, however, that, particularly in the context of a jam, it is the process rather than the product that is central for the musicians.

Moments of an ending

At the point when the sixteen-bar out-head begins after the sequence of solos, the band orients itself to prepare for the ending. In the following analysis I make use of a transcription of the final thirty-two bars of the performance, which comprises a full transcription of the guitar line and a rhythmic transcription of the piano, bass, and drums, along with a sketched mapping of the interactive conduct of the players.Footnote ⁵⁶ In this way the relationship between interactive gestures and musical cues is preserved. Included in the transcription are a number of key elements, significant in their contribution to the creative management of this ending. The transcription is not included in its entirety for economy of presentation, nor is it intended to be an exhaustive piece of performance analysis: the musical elements have been pared down to the minimum required to convey the narrative of the ending, and the paramusical gestures and gazing noted on the transcription are confined to those with a direct bearing on the management of the ending. Figure 1 displays the spatial layout of the musicians as they performed this number.

Figure 1 Relative layout of the musicians indicating the angle of their playing positions during ‘Sunny’.

The ending of this song follows the orthodoxy of much jazz performance in that it can be segmented in the following manner: out-head, the sixteen-bar song structure; tag, the two-bar harmonic sequence that is repeated after the sixteen-bar out-head is completed, using the final two bars of the song form; close, the end of the tag moving into a ritardando and a loss of isochrony.Footnote ⁵⁷ In each of these moments the musicians rely on varying degrees of prior knowledge and interactive conduct as they move towards the end and ‘negotiate’ how this will occur. The first of these three segments is the only one that can be said to have a form that is definable independent of its sonic realization. With its pre-given sixteen-bar structure, the out-head has a written form that is readily available, entextualized within any number of jazz Real Books (for example, the guitarist was able to transmit its form to the bassist in the moments before the start of the performance). The tag, in this instance a repeating two-bar pattern that follows on from the head with a standard II–V cadence, similarly enjoys a pre-given structure, though the number of iterations this pattern will receive is not predetermined. While the transition from the out-head into the tag will be clear to the musicians, provided they are aware of the sixteen-bar form of the song or have a Real Book to hand, the transition from the tag to the close of the song becomes, by contrast, a much less certain affair. In the following sections, I look at each of these segments and the ways in which creativity is manifest through degrees of knowing and conduct between players.

i) The out-head

The out-head usually serves to consolidate the piece and involves a restatement of the tune played at the start. In the performance scrutinized here, the melody is played without undue embellishment, but with one or two modifications that indicate a complex kind of creativity at work. Musicians will sometimes make unusual note choices in a head for creative effect. For instance, saxophonist GB commented on his own rendition of another tune in this session, ‘Yes and No’ by Wayne Shorter, in which he drops just one note in the final ‘A’ section of the melody by a minor third; this could be heard as a mistake, but as he says ‘it's a complete[ly] conscious thing, I'm thinking of it when I'm playing […] in that instance.’Footnote ⁵⁸ The effect is quite startling and signals the complex lineage of an otherwise incidental change to the melody: the drop by a minor third is a direct quotation from the version of this tune performed by Branford Marsalis, another great tenor player, on his album Random Abstract.Footnote ⁵⁹ While not ‘innovative’ practice according to definitions that prize individual authorship, this form of direct quoting is precisely what Ingrid Monson describes as ‘intermusicality’ – a longitudinal reworking of tradition but also an in-the-moment act of creating anew, a process that Jason Toynbee has referred to as a form of social authorship.Footnote ⁶⁰

Example 2 The out-head: bars 1–4 showing guitarist, pianist, bassist, and drummer interactions.Footnote ⁶¹

The embellishment within the final head on this version of ‘Sunny’ comes with no such retrospective acknowledgement of another performance, but the guitarist makes a number of subtle variations to the theme throughout. While this modest, perhaps mundane rephrasing of a mundane tune would be unremarkable to most jazz musicians, it is also an aspect of musical conduct that takes place not simply in the moment with other players but rather within the tradition. Even within the confines of a jam session musicians are reworking and reframing material, even if that material is little more than a stolid transcription of the original performance within a Real Book. The dialectical relationship between creativity as part of a larger cultural scheme and as mundane act seems evident here. Only within the larger framework of jazz culture do these relatively slight alterations and substitutions fall into place as a part of cultural endeavour, and only with the knowledge of prior versions do contemporary reworkings of melodies or solos achieve full significance. Gary Peters has commented that improvisation always enjoys a prehistory, ‘an entanglement of the old and the new’, and whether the reframing involves an active ‘quotation’ from a previous performance or simply the melodic reworking of a tired tune, jazz musicians sense some form of compulsion to add their contributions to the flux within the tradition.Footnote ⁶²

At this point in the ending, the pattern of interaction in terms of either gesture or gazing is at its most sparse compared to what happens in the tag and the close. As the out-head begins, the bassist, drummer, and pianist are all watching the guitarist, who earlier agreed to carry the tune. There is no overt bodily or instrumental gesturing to communicate with the other players, and only thirty-seven per cent of the gaze patterns throughout this sixteen-bar section are directed towards others in the group.Footnote ⁶³ Performance attention at this point appears to be directed more towards tacit individual knowledge than reflexive group conduct. The out-head is relatively risk free, and the three players, aside from the guitarist who carries the melody, are engaged in maintaining the groove and thus accompanying the soloist. The collaborative creativity at this point is therefore focused on support and the consolidation of the performance, before moving on to the riskier undertaking of ending the song.

ii) The tag

Once the band begins the repetitions of the two-bar tag, a wider field of possibilities starts to open up, and the musicians enter it not knowing which of these possible routes will be taken. The guitarist later reported that he had been expecting an ending whereby the tag would go round three or four times, and then probably finish with a ritard on the fifth bar.

The pianist, meanwhile, is clearly going for an extended tag. His accompanying style is highly rhythmic throughout the piece, but during the tag he breaks up the metre and rhythm such that the guitarist, taking on the role of leader, finds it hard to direct the ending through sonic means alone and begins to adopt a more overt strategy in ‘conducting’ the musicians towards the end of the number. One might construe these as manifesting two conflicting creative sensibilities. On the one hand, pianist SC is opting for an extended and quite intense ‘outro’: as he comments, ‘When I'm playing it [‘Sunny’], it generally tends to go on for a long time after, but I think he was trying to do a sort of “repeat the last phrase three times and end”. But, probably because I was getting a bit self-indulgent, I just wanted to carry on.’Footnote ⁶⁴ The guitarist AE, on the other hand, who had initially expected a concise finish to the song, goes for a much more tightly managed ending. He describes the formulaic type of ending that a song such as ‘Sunny’ would often follow in these terms:

These things happen so much that there's a formula for it. Normally, either a phrase at the end is repeated three times, called a three-times ending – which everybody does and which is very boring – and I think in this instance I was trying to be safe and go for that […] and that didn't happen.Footnote ⁶⁵

This divergence in the apparent aims of the group – at least between the pianist and the guitarist – should not necessarily be seen as a creative failure. Improvised musical conduct is by nature inherently messy. What this does highlight, however, is the necessary but insufficient contribution of musical knowledge to improvisation. The comments of the pianist and the guitarist illustrate differences in conduct using a shared body of knowledge (the tagged ending). For the pianist, there was a sense of ‘self-indulgence’ as he pursued an extended ending, whereas the guitarist spoke of trying to be safe by wrapping up the song more formulaically. As the annotations to Example 3 show, over the duration of the tag the ‘conducting’ of the group changes. There is a greater degree of gaze between the performers than during the out-head: forty-eight per cent of all gazing is now directed towards other players. From this point the guitarist increasingly takes charge of the ending: the tag initially sees him trying unsuccessfully to engage with the pianist, and so his gazing towards the pianist at tag ⁺⁵ is intensified by a proxemic move of his head and upper body towards the piano and a subsequent raising of the guitar headstock to signal his intention to end. At the same time the pianist's gaze is held either resolutely down towards the keyboard or towards the bass or drums, but not towards the guitarist. This fits with his apparent ambition to pursue an extended tag. The musical content at this point reinforces a sense of quite different creative aims. At tag ^+2–3 the triplet crotchets of the guitarist are suggestive of slowing down in an attempt to conclude, but it is clear from the semiquavers in tag ⁺⁶, whose precise rhythmic focus is a little wayward, that he has since abandoned any attempt to close at this point. The pianist's extended tremolando on a chord at tag ^+5–7 likewise appears to deny the guitarist the possibility of closing the tune, by creating an animated pedal effect.

Example 3 The tag: bars 1–8 showing pianist and guitarist interactions.

The gazing throughout the tag is dominated by the patterns of the two frontmost players, the pianist and the guitarist. Both the drummer and the bassist are watchful, but still tending to confine their gaze towards their instruments or away from the stand. The conduct of the players is therefore far from uniform. It is worth noting here that, although the bassist in this particular performance enjoys a higher status on the jazz scene than the other players, his role in managing the ending is minimal compared to that of the guitarist. This further underlines the notion of conduct in the moment: shaped by a less individualistic and more collaborative notion of creativity, the bass player's conduct is motivated by his role in the performance rather than his status on the scene.

iii) The close

In the closing moments of the piece the intensity of the interactions increases and the degree of mutual gazing between musicians is greater than at any other point during the three segments of the ending: the musicians direct sixty-three per cent of their gazing towards one another during this critical juncture. The sense of conducting the group falls almost entirely to the guitarist, whose gaze and gesturing become more animated as he attempts to manage the close. As can be seen in Example 4, the guitarist directs his attention mostly towards the pianist at tag ^+10–12, his gaze being accompanied by bodily movement and instrumental gesturing. In bar 11 he also calls out to the pianist ‘Finish’, which may be an instruction or a description, but either way increases the sense of urgency in his closing of the song. The use of a verbal instruction is unusual on the stand, and indicates the degree of close management that the guitarist clearly felt was necessary at that moment. The remainder of the group use gaze more sparsely, but all musicians at various points in these closing moments pay attention to the conducting behaviour of the guitar player. The nature of the collaboration at this moment is therefore rather different from that in improvisatory forums researched by others, in which there is relatively little overt sense of guiding the improvisation to its endpoint.Footnote ⁶⁶

Example 4 Bars 9–13 of the tag leading into bars 1–2 of the close.Footnote ⁶⁷

At tag ^+12–13 the guitarist turns his attention to the drummer as he begins the final iteration of the tag prior to the close. At this point the guitar player marks beat 1 in bar 13. The song moves into the final phase of the ending, the close, marked by a strong ritard and a loss of isochrony. At close ⁺¹, as well as gazing towards the drummer, the guitar player uses the instrument effectively as a baton to conduct the ending, as the tempo decreases and the band slowly moves to silence. Jazz musicians routinely use this type of tempo change to signal the close of a song, but in this particular case two ritardandos are in evidence. The guitarist exhibits the strongest ritard at close ⁺¹ after a downward melodic phrase, a motif which in itself might have suggested closure at tag ⁺⁵ and which is now cut off sharply on the last quaver beat of the bar.

By measuring the inter-bar interval (the temporal distance between the first beats of successive bars), one can see that the drummer and guitarist, from being in agreement about the length of each bar (i.e., from being in time), no longer share the same temporal frame at close ⁺¹. The guitarist's inter-bar interval here represents an increase on the average a tempo bar length of around fifty-six per cent: in other words there is a change of tempo from around MM134 to around MM90. At the same time the drummer appears to slow to about MM122. During this bar, therefore, there is considerable breakdown in synchrony between the players. From the drummer's note choices in that bar it is clear that he is perceiving a shared beat (marked on Example 4 by a triangle symbol at close ^+1–2 as beat 1 of close ⁺²) as a downbeat, whereas the guitar player, from the rhythmic choices he makes, appears to be interpreting this synchronous moment as beat 4 of close ⁺¹. The bassist and the pianist reinforce this group synchrony by joining in with single notes at this point, but it is unclear whether they are cohering sonically or on the basis of visual cueing from the guitarist: certainly their gaze remains on the guitarist at this point. The relationship between knowledge and conduct is here at its most fractured. The drummer attempts to maintain a coherent metric framework as he slows down, drawing on his knowledge of the bossa nova beat, but the crucial synchrony that is achieved on the beat marked by the triangle on Example 4 is a product of conduct – the conduct of the guitarist in being clear with his signals and, just as important, that of the drummer in looking towards him. Although they might have been thinking in terms of different beat categories (‘Are we on beat 1 or 4?’), the sounding result retains a coherence that is achieved through musical conduct, both in the practical sense of the musicians guiding each other (for instance in the guitarist's ‘conducting’ through the raising and lowering of his instrument) and in the broader sense of conduct as an ethical imperative to make musical actions work within the constraints of a creative field – within a tradition, in other words.

Concluding discussion

In the ending of this song the ordinary aspects of getting the work done and the ideological conditions of cultural endeavour are entangled: we see the musicians engaged in the practical, momentary work of stopping together and at the same time subordinating themselves to a creative ideology with its norms and rules for what is appropriate and how things should be done. The mechanisms for enacting these layered creativities are conduct and knowledge.

What emerges most clearly from an analysis of this ending is the changing relationship between conduct and knowledge. As the final part of this song develops, the relationship between pre-given knowledge and momentary conduct is altered. While there is never only conduct or knowledge, and while neither fully represents the ‘moment’ or the ‘tradition’ (conduct requires a knowledge of the way things should be and knowledge requires conduct of some kind to be implemented), the analysis shows a temporally dynamic relationship between the two. As the ending proceeds, the knowledge of chord sequences and tags is insufficient to achieve closure. So while the pianist and the guitarist in this performance had a shared knowledge of the chords to be used, their aims when it came to ending the song were clearly divergent (as the subsequent interviews with the players confirmed), and therefore a much greater use of gaze, bodily movement, and even language became necessary. We therefore see effectively two social mechanisms at work within the same stretch of musical material: one that is mobilized more actively when the sense of the immediate present is at its most acute, and one that is deployed when the performance conditions are perceived intersubjectively to be sufficiently stable for musicians to utilize their stocks of knowledge. Creativity therefore needs to be reimagined not only as a collaborative endeavour but also as a series of differentiated moments in which musicians draw on distinct resources (present conduct and prior knowledge) to fulfil the demand that they finish coherently.

There is a further sense of temporal change at work here though, namely timing and synchrony, and with it a contradistinctive form of knowledge. At the point when the pulsed groove ceases, that is at the close of the song, the sense of shared timing becomes radically disrupted. Up until the end of the tag the musicians rely not only on their knowledge of chords but also on the embodied knowledge of being in a groove together. This provides a metric framework through which shared knowledge and conduct can be articulated: the production of nods and gazes is constrained by collective entrainment just as much as the placement of chords and melody. However, isochrony and metrical alignment dissipate at the close, and it is at this point that coherence can be achieved only by means of intense and focused conducting. At this critical stage the guitarist most actively uses gaze and the movement of his guitar to lead the band, all the while knowing that, without the structuring properties of groove, this is the most risk-laden part of the song. The threat of failure is acute at the point when musical structure begins to dissipate, and so control (in the form of gaze) becomes more active.

Just as the distribution of creative control is not uniform over the period of this ending, neither is this control uniform or static throughout the group. The leadership of the guitar player is plain in this musical exchange, but this assumed role is not without its contradictions. Firstly the guitar player is leader by virtue of stage position and his inhabiting the role of soloist – a common alignment of the spatial and the sociomusical on a jazz stage – but this is not a usual position for guitarists. (If there was a saxophonist present, then he or she would be expected to guide the ending.) Secondly the guitarist might have experienced his own conducting role as being at odds with his position on the scene: that of a more occasional player rather than a full-time professional. His determination to close the song, his pronounced gesturing, and his use of language to achieve closure could at one level be interpreted as strong leadership, but might equally imply that he sensed his own lack of authority in this role. All this suggests that roles are not just inhabited by musicians, but also that they inhabit musicians. There is a certain governmentality at work here: on the one hand the player overtly inhabits a role by leading the rest of the group, while on the other hand he is obliged by the norms of the tradition to take on a powerful role whether he seeks it or not, hence internalizing the rules of the game.

I have summarized the distribution of creativity in this piece as varying over the time of the performance and between the consociates on this jam session. Creativity is also a messy composite of the immediate output of a performed ending and the creative ideologies at work in jazz. Michael Silverstein (whose work on metapragmatics was alluded to earlier) proposes a useful way of understanding this intertwining of the everyday and the ideological. The mechanism that allows the momentary, improvised performance of conversation to both shape and be shaped by cultural ideologies is the inherently indexical quality of language: in other words, meaning is generated not simply by indexical chains within sentences but by means of the indexical function of language towards its past and future contexts. This indexicality can be applied here. To return to one of the above examples, saxophonist GB alters one note by a minor third in the out-head of ‘Yes and No’. That note in itself changes little of the melodic substance of the tune (the ‘indexical chain’ within it), but as a quotation from Branford Marsalis it points to a past musical context. It suggests a plural creativity at work: on the one hand a form of acceptable, mundane conduct within the improvisatory commitments of the moment, but on the other hand a musical decision that places this saxophonist within a tradition of knowledge and prior performance, while also making available for those present a new way of performing this head that might hitherto have remained unavailable. Conduct and knowledge are used here both to preempt the present performance context on the basis of past performances and, potentially, to shape knowledge and conduct in future performances.

Although creativity has been theorized as a system in which individuals create according to the rules and practices of the field in which they work, I have tried to develop this further in two key ways: firstly by emphasizing the collaborative endeavour in so much artistic practice, exemplified here by musicians at a jam, and secondly by suggesting that creating on the fly and a regime of creativity do not inhabit separate worlds but, rather, exist in a productive tension. It is only by attempting to make things work in the moment yet simultaneously within the larger framework of a tradition that we derive a full picture of what it means to jam an ending.
