I am trying to improve my keyboard playing skills and was thinking to take up some Hanon's exercises. I do know a few of them, and I also practice many other exercises. However, I do not want to practice all of Hanon's exercises as I have other priorities which do not allow me enough time.
My question is, out of all 60 exercises, which are the best recommended ones for improving fingers and thus the playing?
I am not a beginner with keyboard and can play a bit. So I would appreciate if someone could please suggest some exercise numbers that I should regularly practice to improve faster.
