This book was a revelation to my piano playing. I am coming back to the piano after being away in all seriousness for more than 20 yrs (minus the occasional sit-down-and-plunk-something-out-session or briefly replaying something I had memorized long ago). I had a LONG way to come, and my biggest weakness has always been sight-reading. It was agonizing to try and find all the notes I needed for a new piece and I had never really been comfortable much above or below the common C hand position (having to always count up or down from a known note). As an adult learner trying to self teach I thought my first stop would be some pedagogical research. My library had a very limited list of books on piano instruction, but they had a copy of this book so this is where I started. My main takeaways: Read something new every time you sit at the piano (play something only once or twice for this purpose) and play at a SLOW tempo to avoid halts and allow yourself the space to get to the new notes (speed up as you gain mastery). Also (I can't remember if this was this book though), don't look at the keyboard. I found the advice to continually read something new to be the most helpful. It helped me crack the music notation code faster than I thought possible. Mostly, I think this was because this method outpaced the speed with which my fingers/brain could memorize a given piece's hand positions and FINALLY forced my brain to learn where the notes on the keyboard correlated to the notes on the page (far up and down the keyboard as you would naturally occur in playing a diversity of pieces). Perhaps this book is longer and drier than strictly necessary (esp to a modern reader), but I appreciated the points it made.
