Johann Friedrich Fasch was a German violinist and composer. His works include cantatas, concertos, symphonies, and chamber music. None of his music was published in his lifetime, and according to The New Grove Dictionary of Music and Musicians in 2014, "it appears that most of his vocal works (including 9 complete cantata cycles, at least 14 masses and four operas) are lost, while the instrumental works are mostly extant." However, his music was "widely performed" in his day, and was held in high regard by contemporaries.Georg Philipp Telemann performed a cycle of his church cantatas in 1733 in Hamburg; an organ work once attributed to Johann Sebastian Bach as BWV 585 is now known to be an arrangement of movements from a Fasch trio sonata; and Bach's Collegium Musicum in Leipzig (a different group than the one founded by Fasch) performed some of Fasch's Orchestral Suites (ten of them, according to Hugo Reimann in 1900, based on his examination of copies in the library of the St. Thomas School, which Reimann said were partly in Bach's hand. Only one of these suites survived World War II; it is in the hand of Bach's student Carl Gotthelf Gerlach] ).
