I searched this forum for a discussion on this important point of technique and came up empty, so I'll post this. If someone knows of another discussion on the Piano Society please point it out and I'll read that one. I never got very good at these; i.e., when I'm doing a piece with fast broken octaves - particularly in the left hand - I have to practice a lot. Excessively, in the opinion of an old man who wants to learn a lot of music in a short time! Of course, I make sure that I master them in an unbroken fashion first, which at least relieves me of the worry about notes. After that it's just raw repetition. One of my teachers (when I was young) had me practice the thumb separately and the fifth (and fourth) finger separately, but that did not seem to speed things up much. Anyone have any favorite, clever, ways of practicing broken octaves???? Or am I paying the price for insufficient attention paid to this when I was young? (I knew my sins would catch up to me sooner or later!) This is in regard to an actual piece that I'm learning for recording (Clementi op 24 no 2) of which I've already mastered the first mvmt, so any help could have a practical consequence for the Society.
