Career
In 1885, Ysaÿe returned to Paris, where he joined the Bande à Franck but also supported the growth of a new aesthetic movement represented by the impressionism of Claude Debussy. Ysaÿe helped promote the work of the new school of French musicians, in Brussels. Ysaÿe contributed his talents as a pianist and a répétiteur.
Although Ysaÿe was an excellent pianist, his fragile health did not allow him to follow the hectic pace of his brother"s career and he instead became a professor at the Genève Conservatory of Music.
In 1918, Théo Ysaÿe died in Nice, France, two days before Debussy. His relatively vast oeuvre has not been published in its entirety, let alone performed as such.
His opus 13, 14 and 15 were published by G. Schirmer in New New York He wrote symphonies, piano concertos, symphonic poems, and chamber music, principally, as well as a requiem.
While he inherited initially the style of César Franck, his later work revealed a clear influence of impressionism.
