Are those Method books for piano? For drummers I suppose it’s like hating Haskall W. Harr, but loving Chs. Wilcoxen, or hating Podemski and loving Goldenberg. I teach with all of them, but notice that my unspoken bias still rubs off on students somehow.
Yes. Of the two, Hanon is closer to the rudiments of drumming than Czerny.
It is a series of exercises that reproduce patterns up and down the keyboard in both hands parallel, by modes, first up the keyboard to work the right hand, and then down the keyboard to work the left hand.
The first book has twenty exercises of 28-30 measures long, and the second book is harder, with all the scales at the end.
I have not attempted the third book, as it is beyond me! Maybe I should try it as a challenge! Right after I teach myself Mandarin Chinese.
Czerny is more like music based on Western Scales. I like the ancient modes, which is probably why Hanon appeals to me!
Hanon seems (to me, anyway!) to be the fastest way to get dexterity back after a long lazy period of not practicing, or an injury, or a vacation.
