At the age of two, he has no business attending music classes. This is retarded and a sure way to make him hate music.
No matter how smart Timmy is for his age, he's at his age. My parents pushed piano lessons on me, so that I could play piano just like my sister, and this didn't work out well for anyone. Music lessons are hard work, and you have to be able to appreciate what you're doing. At least it taught me the value of saying "no" to my parents, which they may or may not have appreciated. 
You guys have no clue what toddler music class is like.

As BB has said, it ain't sitting at a piano bench learning scales (I hated that too, BTW).
Carl is doing that stuff now, and he's pretty good at it, but when he was a tot he went to "music class" for tots - and it was all about playing and singing. He enjoyed it, a lot. All the kids did.
It's like letting kids loose in a playroom with plastercene, construction paper and glitter glue and calling it "art class". They are not busy learning perspective and how to shade a sphere!
