may i remind you - you have used the word 'sin.' as opposed to what, might i ask? playing an entire lesson of music you like is sinful? i guess i am doomed.
thal, what you need is a new teacher. come to pa. you don't, per chance, play with curved fingers do you?
Let me give you an example that i think i might have used before:
When i was learning the Brahms Pag Variations, i could not play the left hand thirds comfortably. Therefore, as i saw it i had 2 options. I could either get out the good old Hanon and practice thirds, or i could simply repeatedly play the actual section of the variations themselves, until i could do it.
Really, i cannot see the difference except that using the Hanon, i am not actualy using the music of Brahms as a drill.
My teacher was neither for or against Hanon, infact i don't remember him mentioning it much. If i could go to a lesson and play well, he did not care how i did it. He did once however, recommend a little Pischna type exercise.
As Liszt said to one of his pupils, "you can wash your dirty linen at home".
There has been hundreds of pages written on this subject and if i read it all, i would not have time to practice. I think that sometimes we must find our own path. Reject what does not work and keep what does and don't spen half your life trying to find out why.
