Can someone comment on how I can develop the muscle memory necessary to play the left hand of the second section of The Entertainer on piano? This is the "oompah bass" section in which the entire left arm literally goes back and forth on each beat - so it's about arm muscles even more than finger muscles.
I've practiced this for months and still play mostly mistakes. Is it ok to look at the keyboard while I'm developing this muscle memory? Because while playing the actual piece, I assume I'm not supposed to be looking at the keys at all.
I've tried developing very short repetitive exercises, played slowly, but even this isn't working...
I'm a beginner (just finished "adult book 2") with three years of playing, and I realize this is an "intermediate piece", but I don't think anything is really stopping me from developing muscle memory on this one section, in one hand, which is just about 12 bars or so.
