A Pianist
I was the one who disparaged it. First off, with no disrespect at all, Chang is not a professional pianist, and not a professional musician as far as I know. I had some personal e-mail with him/her (forgot the gender, though) because I fully believed in the book many years ago. And the book ruined my techniques.
If helpful at all, it is at least severely biased towards a few points which Chang finds useful. The only thing I find helpful is the idea that if you can't play fast by breaking it up into smaller bits, slowly speeding it up may never get you there because the way to play slow is very different from playing fast. That part is truly helpful. But other than that, Chang also emphasised "parallels", claiming that all piano techiques can be reduced to parallel playing and connecting them together. That, if taken to the extreme, may be correct but then Chang oversimplified piano techniques: exactly because not all passages are parallels that we've to practice!! And connecting the parallels is by no means a trivial task as skipped by Chang, let alone the fact that parallels themselves is better NOT played like a chord as Chang claimed!! You lose orchestration by playing parallels fast like a chord and then the broken chord.
The idea that the thumb should NEVER be passed under the thumb is controversial, I've to be objective. But from my experience of following Chang's advice (of not passing the thumb even playing slowly, but move my hand to the next position without the physical connection which I found much later, and is never mentioned in Chang's book), I actually played much much much worse (my R-hand, anyway) until I found Alan's book. I may be the exception, but I don't want anyone to repeat my story.
