I've just picked up a new piece.
I spent from around noon until 3.45 practising a 4 runs (like scales but nothing like the exam sort). 2 - 4 octaves. (short tea-break around 2)
It wasn't self-discipline as much as motivation/application. If I want to play this piece I have to do it.
These runs have to be committed to memory before I can combine the left hand.
I now have to persevere every day until they're there, playable.
The difference is, I'm not working for an exam. .. I want to enjoy playing this piece but it's going to take some work to get there.
Point is, it can be done when need be, so for that poster who can't bring himself to focus on what's necessary, maybe the best is to turn to something else - stamp collecting?
