Hello, I'm finding it difficult to play the octaves section in Beethoven's Andante Favori. My hands are small (can't reach beyond the octave) and get very tired, particularly my right hand because it has a more difficult part with jumps. I normally can't play this passage more than once or twice without a lot of pain and stiffness, but I need to work on it a lot more in order to achieve fluency and accuracy. I would be really grateful if you could offer any advice on technique and exercises. Many thanks.
