My Idol...

Okay, I admit that this is a REALLY old picture but I just remembered it. Can you guess who it is? I'll give you a few hints:

-He lived in the 18th century

-Played viola (like me!) as well as violin

-Wrote his first piece at 4, his first symphony at 7 and his first opera at 12

-There is a saying that God's angels play Bach but in secret they prefer this composer...

-He wrote a Requiem which is considered to be the best piece ever written

-He died at 35 years old of unknown cause and no one knows where he was buried

-He sometimes called himself Trazom

-His wife's name is Constanze

-Everyone has heard of him

-(this is the give-away if you haven't realized already...) His name starts with the letter M
