This Sonata for alto saxophone and piano is in classical form (Allegro-Largo-Presto). It reflects the composer's dual identity both as artist and individual : his classical saxophone studies at the Conservatoire National de Région de Paris-CSP and his jazz studies at the Conservatoire National Supérieur de Paris, as well as his dual Franco-American citizenship. This sonata's harmony, rhythm and structure, are deeply influenced by jazz, but interpretation should remain under the aegis of classical performance tradition. Timothy Hayward's outstanding sonata captures the improvised line, emphasising fluidity and gracefulness. It will sollicit the performer's qualities both as a soloist and as a chamber player.
