I have been fascinated by his wrong notes all my life. It is time to restore in young learners and in listeners of all ages the sense of what is "wrong" in Mozart.
I am reviewing the early piano sonatas, which he wrote at 15. Many of them feature what was to become one of his distinctive devices: an upbeat that goes in the wrong direction. Why lead my ear down when you are going to go up? Isn't that a clear example of a wrong note? Why give me a whole step when my ear demands a half step? Another example of his not doing the right thing.
