Being a composer, I know that
Mozart is God's way of letting you know that you are far from perfect.
While
Beethoven,
Stravinsky,
Haydn,
Brahms,
Debussey, etc etc worked long and laboriously for that one piece, making notes that were reams of paper long and scratching out every other line, Mozart could (and always did) sit down and completely write out his piece in one go, with it being perfectly
orchestrated, notated, and publishable from the first draft. He sometimes wrote entire symphonies in a day.
Opera of course, took a little longer...
Don Giovanni took him all of three weeks to write.
Here's a secret that
musicologists the world over don't want me to tell you, but I will anyways:
MOZART DID NOT WRITE HIS FIRST TWO SYMPHONIES.His
father did.
I'm not saying his
genius is
deprecated by this, or that the quality of his work before he lost all of his baby teeth is poor. I just thought that
antiquity should know.
