I have the same problem. My teacher has this really Yahama grand and the keys weight ton so when I try to play on it, it comes out like a mess. The other pianos at my school are wonderfull but nooooo, I just had to have the teacher who has the piano which is the spawn of Satan.
Hey Keys,What were your other pieces? I'm starting to pick my Gr. 10 rep. now. I was thinking of doing that eerie little Prelude in the knewest RCM book for late 20th cent. Beethoven E major 1st, 2nd, mov., and Ballade in d minor, Brahms.
On a concert I had to play Chopin Walz opus 18, the piano sounded extremely good, but the piano played so heavy All those repeating notes sounded rubbish and my whole piece was ruined. My teacher told me that pianists like Paderewski took their own piano's with them to concerts. That would be perfect, pity that it is impossible.
