"I put quite a bit of study into the horn, that's true. In fact, the neighbors threatened to ask my mother to move out once when we were living out West. She said I was driving them crazy with the horn. I used to put in at least 11 to 15 hours a day. I did that for over a period of three to four years."
—Charlie Parker, from a 1954 Boston radio interview with fellow saxophonist Paul Desmond
