Yep, the relationship between notes and scales (from which chords are built) can actually be SEEN on the keyboard much more naturally than on any other note layout that I'm familiar with. I took a music theory class and we used this paper keyboard printed in a book as a visual aid to our studies. I would actually learn to play the piano and continue music theory study with a keyboard, if I had a keyboard. I simply REFUSE to play notes on that stupid fucking piece of paper. As soon as I can afford one, I'll be purchasing a keyboard.
