Solage (ca. 1360-ca. 1410) is one of the most obscure French composers of the late Medieval period; aside from what can be deduced from the dozen or so pieces attributed to him in the Chantilly Codex, nothing is known. Solage may have been connected to the courts of Gaston Fébus and Jean, the Duke of Berry, and perhaps even to the papal court at Avignon. The esoteric nature of his music marks him as a practitioner of Ars subtilior, a musical development which favored intellectual puzzles, rhythmic complexity, elaborate contrapuntal devices, and unusual harmonies, resulting in music that sounds quite modern.
