After messing around with piano for a few years, I'm still a beginner and not very disciplined with it. :) But I must tell you that playing the two etudes for solo piano at the end of this book has improved the way I play songs in fakebooks. I recommend the etudes in this book, but I'm still working on them. :) You need to know music theory 101 before trying a book like this, but this book is MUCH more accessible than other books (Levine, Montooth, Haerle, etc.) for people like me that aren't very solid in music. I recommend this book to singers trying to figure out how to play fakebooks. :)
