Carl Friedrich Abel (22 Dec 1723–20 June 1787) was a German composer. A fine player of the viola da gamba, he composed important music for that instrument. Abel with Johann Christian Bach established England's first subscription concerts. A manuscript symphony in the hand of Wolfgang Amadeus Mozart was catalogued as his Symphony no. 3 in E flat, K. 18, but was discovered late to be the work of Abel, copied by the boy Mozart—for study purposes—while he was visiting London in 1764.
