One of the most notable composers of microtonal music, he was awarded the Jules Léger Prize twice, first in 1979 for his Musique pour Champigny and again in 1993 for Yquem. Some of his other awards include the Composers, Authors and Publishers Association of Canada's Micheline Coulombe Saint-Marcoux prize in 1987 for Barbaresco and the Serge Garant Prize from the Émile Nelligan Foundation in 2000.[1]
As a pianist Mather has displayed a strong commitment to performing new music by himself and by other contemporary composers. He has performed in many major performance venues and music festivals, often appearing with his wife, pianist Pierrette LePage, in duo-piano works. The husband and wife team have also partnered on several recordings. He served as director of the Société de musique contemporaine du Québec from 1966–1981 and later served as treasurer.[1]
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.[2]
In his composition he still uses the famous Wyschnegrasky's principle of non-octavic spaces.[2] 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.[3] His compositions are also strongly influenced by his love of poetry and wine.
