I studied with Sylvia Kersenbaum while pursuing my music degree. Here is a musician who can play pretty much what she wants. Here is her website.
Check out her work if you are so inclined.
After nearly 20 years of not playing (long story told somewhere else around here) I'm back taking lessons from a different teacher whom I really enjoy, and I spend my lunch hour catching a few minutes of time at the same practice rooms with the same (sometimes crappy) pianos that I practiced on as a student.
Sylvia retired a few years ago and no longer teaches, but she does still perform, recently playing the Beethoven 5th concerto and Brahms 2nd Concerto year before last as well as solo concerts.
The part about her being an inspiration is this... I often see her in the practice rooms, on the same crappy pianos the rest of us have to play on, and she's doing everything she required of us... scales, arpeggios, sections, hands separate practice, SLOW SLOW SLOW....
Yesterday, for instance I saw her practicing on an ancient Baldwin Hamilton upright with just the left hand thumb slowly... a descending line Ab3-G3-F3-Eb3, using exaggerated rotation. I knocked on the door and exchanged pleasantries and asked what she was working on..
She told me she was relearning the Chopin Ab Major Polonaise
and was working the thumb alone because... 'once you have the thumb, the rest is easy'
I've asked her in the past why she comes 'up here' to practice instead of her grand piano at home and she says she likes the atmosphere and the young people and 'besides... if I can make music sound good on these pianos, a nice instrument becomes simple'
She always starts with scales - slowly - then Bach, then gets down to 'business'.
So ... when I start to think of reasons not to practice... :-)
