This chapter addresses the role of the audience in the creation of successful and the meaningful performances, and it explains how the audience is perceived and what kind of interaction takes place between the musicians and the audience. The cultural and physical circumstances of performances make playing music a social practice. The centrality of the audience was made very clear in the interviews, and the respondents had high expectations of audiences. As Riikonen has pointed out, live performances are therefore central to their professional activity, and the audience is an essential component of them. The Becker noted that the jazz music is also a service occupation, whose clients were able to direct what they did. This means that there are two parties to a performance: the musicians whose 'full-time activity is centred on the occupation and who's self is to some degree deeply involved in it' and the audience whose 'relation to it is much more casual'.
