and Milhaud quickly became one of his more important mentors. He continued to study with Milhaud and with Simone Plé-Caussade, Lazare Lévy, and Olivier Messiaen at the Paris Conservatoire from 1959-1961. In 1964 he received a Master of Music from Stanford University where he was a pupil of Leland Smith and Roy Harris, and in 1967 he earned a Doctor of Music from the University of Toronto. Music Mather is a composer of orchestral, chamber, vocal, and piano works. A disciple of Ivan Wyschnegradsky, his music often employs microtonal scales. Though he was distrustful towards microtonal music since he heard Alois Haba's Music, his meeting with Wyschnegradsky in the seventies was crucial for his aesthetic and his use of microtonal scales. As a pianist, he and his pianist wife, Pierret Mather, have performed many of Wyschnegradsky's pieces. In his composition he still uses the famous Wyschnegrasky's principle of non-octavic spaces. He wrote many works using this technique and notably his Poème du délire ("Poem of Delirium") a tribute to Alexander Scriabin (as a reference to his famous Poem of Ecstasy and Poem of Fire), an influential figure for him and Wyschnegradsky. His compositions are also strongly influenced by his love of poetry and wine.
