In a recent issue of this journal, David J. Levin proposed an approach to evaluating the work of directors and producers of opera. The idea that one might be able to theorise the difference between good and bad stagings is appealing, not least because many of us would like to feel able to raise the standard of debate on this subject. Most public discussions of opera productions (or at least of those productions that generate public discussion) can be predicted in advance, more or less verbatim; the persistence of the arguments used on all sides is in itself enough to suggest that little progress is being made. On the other hand, it is not easy to see how academic debate contributes. Theatre is where operas enter public discourse. Performance might seem like a decisive act of interpretation – choices have to be made about how to present the given work – but, paradoxically, it also marks the point at which opera escapes the attentions of the academy in favour of a constituency which is (presumably) less grounded in theory and less committed to consciously interpretative acts. With understandable reservations, Levin suggests the use of commercially available videos to analyse details of a staging, but details of this sort are not likely to contribute significantly to a theatre audience's experience of how a production works and what it has to say. Videotape permits us the mastery of freeze-frame enquiry, and at the same time confines us within the flattened perspective chosen at each moment by the camera's eye. Both its advantages and its drawbacks are incommensurate with theatre, where (especially in opera, with its simultaneous but distinct modes) the stream of information is diverse and continuous, and our eye moves in relative freedom, never capturing the totality of the stage. One might draw an analogous distinction between academic criticism, which works by isolating certain elements of the ‘text’ or its contexts and subjecting them to intense scrutiny, and the more holistic act of sitting in the opera-house watching a ‘work’ unfold. The pause button creates a sequence of discrete images submitted to the critic's intellectual play. In the theatre, a staging is more likely to achieve its effects through what we might call its ‘feel’, its general character and stance. When Peter Sellars set Così fan tutte in a diner, the air of incongruous modernity – conveyed through costume, set, the characters' ways of behaving–must have determined the audience's sense of his interpretation far more powerfully than (for example) the fact that he had Ferrando and Gugliemo sing ‘Secondate, aurette amiche’ in their own characters rather than their assumed ones.
