all my music sheets are on tap electronically on the clavinova, music videos can be played along to on the dvd player
and if i am blanking out on any chords, a ginormous roedy black complete keyboard chord poster [ link ] is right in front of my face
but for all those times when i have a tune in my head and i can't tell if the next note is higher or lower
nothing in the world's going to help with that
