Keyboard Musician for the Adult Beginner

Both my wife and I have been recommending this book for many years to adults wanting to learn the piano. As part-time piano teachers, we found that the lessons progress at an very good pace for most adults. The choice of songs used in the lessons are tasteful mixing both folk and classical traditions. This book also works well for someone with some music reading background but no previous piano playing experience. This book uses the classical approach and doesn't offer instruction on specific styles like rock, jazz, blues, etc. Overall, I still think it's the best adult piano method book that I've come across so far.
