Gossec, François Joseph (fräNswäˈ zhôzĕfˈ gôsĕkˈ) [key], 1734–1829, Belgian composer; pupil of Rameau. In 1784 he organized the École Royale de Chant and taught (1795–1816) composition at its successor school, the Paris Conservatory. Enthusiastic about the French Revolution, he wrote many works to celebrate patriotic events, such as a Te Deum for 1,200 singers and 300 wind instruments. Among his works are chamber music, more than 30 symphonies, and many operas. His clarity of form and innovations in orchestral color strongly influenced the development of French instrumental music.
