By the way, that tetris theme doesn't have a base clef, does it?
No, it's a guitar score. The notes on the guitar only go down to about the middle of the bass clef, so we just use a single treble clef and ledger lines where necessary.
Thta Midi is very good ED is that you, and what are you playing it on?
It's not me, it's from the same site as the PDF. ( http://dirk.meineke.free.fr/ ) It was sequenced using a program called TablEdit (guitar tablature editor).
