I've always enjoyed "Music C" in the original gameboy version of Tetris. Its a lovely little two voice baroque piece.A couple of years ago, I decided to transcribe this piece by ear to sheet music so I could learn it. It was a very painstaking process, and I didn't know how to properly place stems on notes or even which stave they should reside in. But I eventually got the whole thing down, and learned it.Three days later, I went to the library seeking out books on baroque counterpoint (just for the hell of it).I grabbed the first book my hand landed on, called "Counterpoint in the Style of J.S. Bach". its around 400 pages long.I flipped it open and the first thing I saw was the very piece I had transcribed.Its the minuet from Bach's french suite in B minor! Thats the most amazing coincidence that has happened to me with piano music. Remember I had no idea the little tetris piece was by Bach!details: the tetris piece lacks one of the sections of the original piece, and is a fourth lower than the original.
