To clear up any confusion, in the gameboy version of Tetris there were themes A, B, and C (see below). In the NES version, there were themes 1, 2, and 3 (1 was dance of the sugarplum fairy, 2 is the same as B). So I made this sort of out of request after submitting my last one, and I suppose I'll submit it to the SoFurry contest as well. I sort of ran out of different keyboards to use, so I figure since I used 2 pianos for A and 2 harpsichords for B, I'd just pick one of each, and I think it came out remarkably well.
That makes 4 Tetris submissions in 1 week xD... Enjoy!
