Résumé
Free improvisations are unprecedented and underdetermined: their content and the way they unfold are not known in advance. Improvised performances have to be actively shaped over time. To do so, the improviser must articulate his embodied experience. In other words, he has to make sense of his experience' by relying on his bodily know-how. And so this process of improvisation personally involves the improviser. Therefore, it should be a relevant point of entry for the study of his musical "personality" (or "identity:' see I Iargreaves et al., 2002). Firstly, to put this argument forward, we link free improvisations and personality in the light of embodied (enactive) and dynamical approaches. However, free improvisations are often played as a group. Secondly, so as to link improvisations and personality in the context of human interactions, we present a pedagogical method of free improvisation (the Kaddouch pedagogy; Kaddough and Miravete, 2012) in which interactivity between learner and teacher is a core aspect. Then, we will show that the process of interaction by itself allows to unveil, to foster and to expand both improvisational skills and musical personality. Finally, we propose theoretical bases for this method, plus some explanations dealing with its effects.
