Going to Mannheim and meeting the Webers

He and his mother moved on to Mannheim, became pleasant with the Mannheim musicians, did some teaching and playing, accepted and partially fulfilled a flute music commission from a German surgeon, and fell in love with Aloysia Weber, a soprano, the second of four daughters of a music copyist. He has also written numerous sonatas for piano, some with violin. He put a scheme to his father for traveling with the naive and reckless Webers to Italy, and met with an angry response from Leopald.
