Pour une génétique de l'improvisation musicale - première partie : éléments théoriques

Résumé En

The project of a Genetics of musical improvisation can in itself seem quite paradoxical. On the one hand each improvisation appears to us as a pure singularity, an ephemeral musical perfor- mance without past or future, and on the other hand, each improvi- sation bears the trace of a process of memorization, incorporation and reinvention that are consubstantial with improvisers’ practice and that unfold from one performance to another, thus making any act of improvisation a sort of permanent work in progress. We will rst identify the conditions for the possibility of a Genetics of musical improvisation in Jazz and other types of freely improvised music. In doing so we will introduce the notion of “improvisational project” and suggest a dynamic model of the genetic relationship at play in improvisers’ work.
