This paper utilizes the vocabulary and methodological concepts of field theory to explore how play can arise in and through performance. Field is defined as a space or potential for action. The action of play is grounded in an open and expanding space which through a dialectic interplay of feelings motivates self-exploration. The action of musical performance is grounded in a reaching out movement through which the performer forges and sustains a musical voice. The field can create a space for play when the music-making re-directs or challenges the focus of the musical voice. The methodological approach recognizes and respects differences in the way music is made in different cultural traditions. It also articulates a need to develop instructional strategies which treat musical style as a ritualistic process and which define the role of the teacher as a musician.1
