Born in Zerbst, he was the son of the composer Johann Friedrich Fasch. He was initially taught by his father. In 1756 he began service at the court of Frederick the Great of Prussia, where he served as deputy to Court harpsichordist C.P.E. Bach, whose post he attained when Bach left the court for Hamburg in 1767. In 1791 he founded the Sing-Akademie zu Berlin which quickly became an important centre of Berlin's musical life. In its concerts Fasch promoted the music of J.S. Bach and other masters of the Baroque period, as well as contemporary music. The Akademie was visited by Beethoven in 1796. Fasch also composed numerous works for the Sing-Akademie. His Mass for sixteen voices, a virtuosic mass accompanied solely by organ continuo, is a choral masterpiece of the late 18th century.
