That's A Lot of Ivory

I'm spending some time at lunch these days trying to catch up on old, saved emails and links to articles I'd like to read. So, I just read a statistic that there are at least thirty million chil­dren/students in China currently taking piano les­sons.

Thirty.

Million.

I wonder how many are playing the violin, the oboe or the tuba?
