A largely self-taught composer, his output includes several motets, two masses, a few patriotic songs, works for solo organ, and the operetta L'Intransigeant (produced in Ottawa in 1906).
[1] Born in Montreal, Tremblay, along with Alexis Contant, was one of the first major Canadian composers to be trained exclusively in his native country.
At the age of 12 he began studying music with Father Sauvé, the organist at Saint Joseph's Church in Montreal.
His pupils in that city included Joseph Beaulieu, Wilfrid Charette, Oscar O'Brien, and his own son, the composer George Tremblay.
[1] In 1920 Tremblay moved to Salt Lake City, Utah to assume the post of organist at the Cathedral of the Madeleine.
