Commentary on: "Perception of Structure in Collective Free Improvisation and its Context Dependency" by Arthur Faraco

This short commentary on Arthur Faraco's target paper investigating the perception of structure in collective free improvisation addresses the question of whether the concept of the "interrupt generator" can be used to explain the segmentations annotated by listeners. In addition, the commentary points to opportunities for further modelling of the musical and perceptual data through the use of modern tools from music information retrieval (MIR).
