Oops, its in A minor- forgot to menton that!
Ok, my piano teacher gave me this to look over for this week (as he forgot dream of olwen ) but I actually really like it. I listened to a version i downloaded though, and after the few chords at the beginning there is a big run up the piano- my version doesn't have this. However the song I listenned to was a remix of the classic, and I thought maybe it had been added in.. can anyone verify this for me? Thankyou

After the timpani roll and the cascade of double octaves coming down, there should be a cadenza like A minor arpeggio going upward, then down a bit, then further upward, before a bass F and a chord and a bass G# and a chord (I think) before the main tune.

That's exactly right!
