I don't think it matters.Longer arms means less leaping, but F=M*A means you need more energy to move your arms.Though i can immagine that when somebody is really FAT, its more strenious to keep playing long periods, and when you have big/thick fingers, jumping far is hard too.Gyzzzmo
I'm tall and thin, not to mention I have large hands (comfortably, I can stretch an 11th). So, piano playing is relatively easy for me. I have no trouble leaping, because my hands are large/arms are long, and my hands are thin, but in a masculine way, and since I'm so thin, I can move my arms fast.
It actually means that more force is used, but not necessarily more energy, PHYSICS!!Gravitation potential energy = m*g*hThat IS energy, so if you are those lobby fatty wobbly people, you can play rachmaninoff with quite some volume.
i have small nimble fingers, i can only stretch an octave or a ninth occasionally, but i am of average height (im a girl) 5 foot 6, and have quite slim arms. my hands start to hurt when i play lots of octaves and i used to sometimes get pains up my arms if i played too much without warming up, but now that doesnt happen probably because im playing more. i can play quick runs and things better than big chords but i can still play nice and loud i guess it would take more energy for me to do that though.
Generally, I think massive arms and shoulders will help with use of weight transfer to get a big sound, and good legato. It's kind of like how the big guys make great opera singers.
well, for someone like me with long legs, Kawais can be a problem because I can't put my knees under the piano. So when I play on one in competition, the fact that I played on a Yamaha (which I can put the knees under) in practice might screw me over.Generally, I think massive arms and shoulders will help with use of weight transfer to get a big sound, and good legato.

force=energy: physics
TOTALLY INCORRECT!Get you physics right next time before you start arguing with me, or any chemistry or biology questions, oh yea, and mathematical concepts.Force is measured in NEWTONS, which is F=ma, mass times acceleration. it means more force is applied, but not necessarily more energy, you can understand this concept provided that you have a functional brain.The energy type we mostly talk about in piano playing is kinetic and gravitational potentialKinetic energy = (m*v^2)/2Gravitationl potential = m*g*hIt it uses a mixture of both kinetic and GPE, and it is measured in JOULES! That is the unit for measuring units.Next time, please revise or learn or get a brain before you start talking about things over your level.
