Okay I get your drift .So lets say I wanted to do some crazy trill or tremolo or repeated note group like say in Liszt Hun Rhaps. So the best way to actually practice the trills is to make the repertoire itself (cut it up into whatever manageble) sections and get your "hanon" from there? Okay sounds like what you've been saying all along, I think. Am I thinking what you're thinking?
Who said Hanon isn't music by the way? Shostakovich even put his excercises in one of his piano concertos, to get his son practice Hanon! Well, what do ya say bout that, bernie?
Yes, that is what I have been saying all along.
