Thomas Jefferson once met Mozart to commission a piece for his wife. However, he was put off by Mozart’s personality, and ended up not going ahead with the idea.
Mozart had a sister, Maria Anna, who was just as talented as he was. She was forced to stop playing and composing professionally at the age of 18 because she was a woman.
Mozart was one of the first music pirates. Fourteen year old Mozart, while on a visit to Rome, heard Gregorio Allegri’s Miserere once in performance in the Sistine Chapel and wrote it out from memory, thus producing the first illegal copy of this closely guarded property of the Vatican.
