How did informal and participatory performances change the roles of composers, performers, and listeners?

In informal and participatory musical performances, the traditional boundaries between composers, performers, and listeners are often dissolved, consolidating these roles into a single participant.1

In these settings, the act of music-making becomes a collaborative, spontaneous process where all attendees act as participants. Rather than a composer dictating a fixed work to be interpreted by a performer for a passive audience, the participants interact to invent and realize an artwork collectively. Because this creation is dependent on the specific interaction of those present, the resulting performance is unique and cannot be replicated in exactly the same way again.1

This shift contrasts with more formal traditions, such as Western classical performance, where the performer typically acts as an interpreter of a composer's notated work. While some modern electronic music allows composers to communicate directly with audiences—bypassing the performer as interpreter entirely—participatory performance moves in a different direction by democratizing the creative act itself, turning the listener into an active co-creator.2341
