Discipline

The film Amadeus dramatizes and romanticizes the divine origins of creative genius. Antonio Salieri, representing the talented hack, is cursed to live in the time of Mozart, the gifted and undisciplined genius who writes as though touched by the hand of God … Of course this is hogwash. There are no ‘natural’ geniuses … No-one worked harder than Mozart. By the time he was twenty-eight years old, his hands were deformed because of all the hours he had spent practicing, performing, and gripping a quill pen to composeā€¦
As Mozart himself wrote to a friend, “People err who think my art comes easily to me. I assure you, dear friend, nobody has devoted so much time and thought to composition as I. There is not a famous master whose music I have not industriously studied through many times.”
