The Sonatine For Flute And Piano By Pierre Louis Joseph Boulez, And Its Contribution To Modern Day Flute Performance, Myles Roberts

Dissertations

Following the Second World War, Pierre Louis Joseph Boulez developed a less-than-ideal reputation for his strong views within the modernist movement, and the reaction to his Sonatine for flute and piano reflected these polarized feelings. The Sonatine was initially written for the French flutist Jean Pierre Rampal, who after a failed negotiation with Boulez, refused to premier it. The work was finally premiered by Jan Van Boterdael and Marcelle Mercenier in Brussels in 1947, and the first performance of the revised version was held in Darmstadt in July 1956, by the Italian flutist Saverio Gazzelloni. Gazzelloni’s performance had the audience …
