You're learning the tempest for a competition, and you call it a "song"? Something doesn't smell right, here. You ask for tips - maybe you could be a bit more specific and we can tell if you're really a legit pianist. You're really quite vague, here.
What exactly are you having a problem with though? The tremolos?
Well, never mind about the recording, this won't let me upload it. I'd like some advice on the pedal usage during the tremolos. In measures 21-38, each chord has two notes that are staccato in the bass, so I know I can't hold the pedal all the way through; but then there are whole notes almost every other measure, so I know I can't lift the pedal after those. Then there is a staccato sforzando in all the chord through 29-38, so...? Some pianisits have told me to lift the pedal at every note in the bass during those measures, but I really hate the sound of that. Advice? Also, same kind of thing I'm having trouble with in m. 103-122, where the entire bass is staccato except for the half note at the beginning of the measures. In m.123-125, with the Gmaj and then Bbmaj triplets in the left hand, I cannot seem to make those clear. Any ideas of how fingering or pedal could help with that? Thanks! - Lydia
