Josef Mysliveček
A lot of his music sounds like some of the early works of Mozart. Mozart, in return, uses several musical themes from compositions by Mysliveček. He also made an arrangement of an operatic aria by Mysliveček's: "Il caro mio bene". Mozart changed the words and wrote "Ridente la calma," KV 152 (K⁶ 210a) for soprano with piano accompaniment.
