I'd rather not keep posting and make it sound like I'm trying to put you down but I'm afraid if you're finding it difficult to play VII's main theme then you're definitely not a Grade 7 pianist, when Grade 8 is the highest you can possibly go, particularly if I can play it at Grade 1.It's not low in the US, but I don't really know (Since I'm in Canada). Grade 7 in Canada is pretty high. I've been playing piano since I was 4, and it wasn't quite difficult to get up to grade 7.
Grade 7 piano music is quite hard to play, unless you're really experienced in it. In the Celebration Series - Piano Odessey (or however you spell that word, I don't give a shit about hard grammar) I play few pieces for the exam. Here I will list them :
1. Rondo Toccata
2. Solo in F Major
3. Fur Elise (I mastered it XD )
4. Grief
5. Etude in E Major (or minor...?)
That's all of them.
But for my school's talent show, I will be playing Aeris' Theme *squee* and I'll be videotaping it. =D
Anyway, I'll be getting a bass guitar for a birthday present. =) Do both cello and bass guitar have the same notes? Because if they do, I'm DEFINATELY getting a bass guitar.
I'd be an expert already on the first time playing it.
However, good luck with the talent show.
