Abstract

The musical method of collective improvisation expresses a conception of the game whose democratic-emancipatory basic attitude suggests comparisons with the concept of the ideal speech situation formulated by Jürgen Habermas. This presumption is explained in more detail within the framework of an introductory approach to collective improvisation as a process of relationship characterized by interactivity and synchronicity. After a discussion of improvisational action in music with regard to theoretical, historical and psychological aspects, the various developmental stages of free or collective improvisation that emerged from free jazz in the 1960s will be presented. Subsequently, the collective improvisation will be discussed with reference to the concept of the ideal speech situation and located in an intercultural context. The sublimation of idiomatic, culturally shaped forms of expression demanded by musicians like Derek Bailey will be explained by the individual development of a characteristic sound language on the instrument as equalizing for the asymmetrically shaped dialogue forms of this situation.
