Comparative study between editions of Sequenza I for solo flute by Luciano Berio: subsidies for the understanding and interpretation of the work

This thesis presents an analytical study of Sequenza I for solo flute, by the Italian composer Luciano Berio (1925-2003), focusing on two editions of the work. The first one, from 1958, uses proportional notation and was published by Suvini Zerboni Editions. The second one, published by Universal Edition in 1992, was reviewed by the composer and uses traditional rhythmic notation. Among various motivations for carrying out this work, I mention the peculiarity of a composer rewriting his own work 34 years later, centering his changes mainly in the rhythmic notation; a survey of issues regarding interpretative practices and focusing on works for flute; and the representativity of Sequenza I as a canon of the flute repertoire, which study is indispensable to the Twentieth Century flautist. Placing myself both in the role of performer and analyst, I look for reflections concerning performance practices, as I seek to develop myself in both fields. In conclusion, I found a relationship of mutual collaboration between musical analysis and performance, which really clarifies structural aspects; and an influence of Berio\'s experience within electroacoustic composition in writing this piece for an acoustic instrument (AU)
