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.
