The Do-It-Yourself Handbook for Keyboard Playing

This is a great book. I learned keyboard from it years ago (using the 1982 edition). I'm now back to order some more for my kids who are learning keyboard now. This is not your traditional approach to learning piano----much better. However, I'd rather it not assume so much that you know musical notation already. I had some knowledge of notation starting out so book was good for me. However, I think you can learn keyboard (playing popular music) without starting with traditional notation (which initally can be so frustrating).
