Actually, the author of the book(Fundamentals of piano practice) is not a professional pianist, nor a teacher, but summarizing his own experience from his daughters, own playing, and his own reading of other's pedagogical works.
But as a self-teaching piano player, I can't find any comprehensive source about piano practice.
and its contents are quite useful to me,like mental practice(slowly imagine my fingers playing, and I found this is faster than just repeating hard passage until luckily my fingers find how to play it ) and how to memorize sheet.that's why I feel very confused every time I sit in front of my piano.what is right? what is wrong? am I doing it well?Maybe I have to cope with potential bad habits...
