Hello, fellow Piano Street-ers! I have a problem that's been bugging me throughout my entire piano life (~10 yrs of lessons, then another 5-10 yrs of playing recreationally without a teacher):
Most of the larger romantic works I love require long passages of rapid 16th note octave scales, which I can't manage to execute fast enough without hitting some nearby notes. This brings me to my question:
Does anyone with similarly sized hands (can only reach an octave with 1-5 fingers at edge of keys) have any advice or success stories on being able to play rapid, long, blocked octave runs? Before that, some relevant background on hand size, stretches I have tried, the pieces I am trying to play, etc.:
I have tiny hands - my left hand can reach an octave cleanly, and my right hand can reach an octave but just barely. I can only reach the octave on white notes with my right hand if I play *at the edge of the keys*. I can do large broken chords with no problem (via rolling method) and can do short spurts but can't do the long octave runs necessary in so many of the works I like - I especially struggle with chromatic octave runs, since my right hand has to shift from the edge of the keys (to play the white notes) then move up quickly to play black keys, repeat, etc. (Fortunately, I can play a black key octave with 1 and 4, so that alleviates some of the discomfort, but I can't comfortably play a white key octave with 1 and 4 without hitting something else at present or without having to angle my entire wrist inward dramatically (thus my whole body must ship, since my arm and elbow dig into my side - it takes too much time to do quickly.)
I've tried many of the things mentioned in various forum threads here, but most of them either don't apply or haven't worked.
Stretching: My hands probably aren't going to stretch anymore - I've used all sorts of stretching devices prescribed by my teacher when I was a kid, and my right hand when stretched out is nearly in a parallel line to the keys (ie: my hand is nearly doing a "split") when I play the octave. I can Therefore, I don't have enough "arch" room in the right hand to play fast blocked octave runs without hitting someone else. I don't think there's much more room (if any) for them to stretch out without injury, since I've been playing since I was a kid and am now 30 yrs old.
Bouncing: I tried bouncing, but this won't work with my right hand - as I mentioned above, I can only play the octave with my fingers and wrist at the far edge of the keys (so I can't easily bounce with the right hand esp in chromatic octave scales, due to not being able to play the octave in the "middle" of the keys).

Similarly, I tried using my shoulders more, but that didn't work.
Wrist: I tried using wrist movements, but this doesn't work, because I need my hand span to be fully outstretched to reach the octave (wrist movements tend to mess this up) - not sure if I'm doing something wrong here.
Adapting the piece to fit a small hand: While this works for blocked large chords (where you can roll or drop a note), sadly this doesn't apply to long octave runs in 16th notes - you either hit the octave notes or you don't - there's nothing to drop or roll.

Choosing "easier" pieces for small hands or pieces without octave runs - I've seen this suggested elsewhere, but the heart wants to play what it wants to play! I'm determined to learn Hungarian Rhapsody, Chopin's Winter Wind Etude, Liszt's Mazeppa and La Campanella, and hopefully some challenging, beautiful pieces by Scriabin, Rachmaninoff, Schumann, etc. that all have rapid, long octave runs. They're on my piano bucket list, and I love them to pieces.
I've attached some visuals to hopefully help illustrate (will also add them to the initial post).





Does anyone with similarly sized hands (can only reach an octave with 1-5 fingers at edge of keys) have any advice or success stories on being able to play rapid, long, blocked octave runs?If so, I'd love any advice you have, as I've been struggling with this for ages. Thanks in advance, and your input is much appreciated.
