When did Mozart begin music lessons?
Mozart began his early musical training with his father, Leopold Mozart. Leopold was, by then, an already famous musical composer.
At the age of three Mozart, watching his sister's keyboard lessons, began picking out thirds on the keyboard by himself. His father, Leopold Mozart, was a minor composer himself, and began teaching Mozart. By age 5 Mozart was playing his own tunes, which his father wrote down for him. His father was the only teacher Mozart ever had, apart from his own learning from other musicians and composers.
