So, I've been struggling to continue studying Chopin's Ocean Etude. I enjoy it when I work on it but find difficulty summoning willpower to continue, due to how difficult it is to play this piece anywhere close to speed. I can read it slowly and accurately. Obviously, the thing that makes this piece difficult are the hand position changes that occur in the different sorts of arpeggios.
I haven't tried this yet but I wondered if other people do this and if it is effective: Practice *just* the hand position changes. In other words, move back and forth between them. Where my pinky would be replaced by a thumb, or thumb by pinky in the other hand, I might be landing on an octave (easiest for some reason), major or minor ninth, or 10th. It seems like these movements cause the most flubs. So if I just practice those movements, should this help?
To put it another way, so far I've only been practicing by playing the piece as written, slowly, without putting a very microscopic focus on the specific technical problems.
