Discursos polifónicos na obra de Luciano Berio (1925-2003): o conceito de amálgama do timbre na análise e interpretação da Sequenza V

Abstract

This paper aims to analyze the Sequenza V of the composer Luciano Berio, focusing on its interpretation. The analysis proposes a discussion on sound processing that results from a polyphonic game of multiphonic character, fundamentally based on the sound. This work seeks to contribute to the fostering of reference in the area, especially on interpretative issues regarding the contemporary repertoire. The methodology resorted to know the literature, the music analysis and practical study and performative construction work on the trombone. The process of preparation and work of study on trombone followed the four dimensions of analysis proposed by the composer - temporal, pitch, dynamic and morphological - and are expressed in an interview published in 1980. This research attempts to show, yet, as the idea of latent polyphony is expressed in the Sequenza V and as gradually intensifying throughout the work.
