 Beyond this, spectators must be able to determine the style in which a performance occurs in order to be guided to relevantly correct expectations. Consequently, performers must make stylistic choices as well. For it is actually sequences of features (resulting from sequences of choices) that give shape to a performance over time and guide spectators’ expectations. This will be so if the sequence is a convention governed by some overall goal the performers have. And again, none of these tasks, especially since stylistic choices demand coordination among the performers, is particularly easy to succeed  at.[3]
