This is a very good book for a guitarist to get the best out of a keyboard in a short time. I have played guitar for over 50 years, including skiffle, rock, jazz and formal classical training and so when I sat down at the piano I had some idea of what to do.
This book has helped me to disipline my learning experience and enabled me to get more pleasure from my playing.
It is also of value to anyone without guitar experience because it teaches harmony through the structure of chords.
Well worth the money.
