ABSTRACT
Musical ensembles provide instances of human interaction that involve ‘a degree of intimacy and subtlety possibly not equalled by any other kind of group’ – characteristics that have become increasingly apparent throughout this text. Improvised ensembles may provide a more direct means by which non-performing observers can see the impact of musicians’ interpretations on subsequent musical events. Through the framework of inter-reaction, it is possible to see how quickly the musical landscape evolves due to the performances taking place. Upon Roberto’s departure from his previous musical line, he introduces a new texture to the ensemble. The creation of musical intention and interpretation emerges from a host of informants. In ensemble performance, the emergent musical intentions of the other ensemble members may act as another informant. Beyond its applicability as a means to analyze ensemble interaction, inter-reaction may provide further insight into general musical qualities themselves.
