L’intersezione fra i ruoli del compositore, dell’interprete e del direttore dell’esecuzione nell’improvvisazione degli anni Sessanta e Settanta del Novecento: l’esempio di Individuum- Collectivum di Vinko Globokar (1979-)

Abstract

This article examines the intersection of the roles of composer, performer and conductor in contemporary music, particularly in the improvisation of the 1960s and 1970s. After recalling the main American and European trends that led musicians towards formal indeterminacy from the late 1950s onwards, the text focuses on the multifaceted figure of Vinko Globokar, at once composer, instrumentalist and conductor, and in particular on his 'open work' Individuum-Collectivum (begun in 1979 and still unfinished), which represents an interesting and complete synthesis of the aforementioned trends. Written in the form of an open workbook, it contains verbal, graphic and notational indications for composing and improvising for competent or novice musicians, as well as others formulated with the intention of allowing one to reflect on the conceptual value of a given performance. In addition to the artistic dimension, this work also reveals a profound didactic value, both at the level of composition and at the political and social one: improvisation in fact implies the equal involvement of the participants and thus prefigures a strongly democratic social model.
