I am trying to get more classical music scores into the repitoire, would anyone be able to advise me as to where to get them?
It's really a crapshoot. I suggest just going to a store and picking up CDs, because it's hard to find torrents of anything like that - it's not popular enough among people who use torrent programs.
Anyway, you could check out French romantic composers, such as Debussy, Godard, Ravel, and Saint-Saens. I find their compositions to be a little less uptight than what most people imagine when they think of "classical" music, and it's more freeform and expressive. Godard is the most standard-sounding of the four, I think.
For particular pieces, I love Godard's Suite de Trois Morceaux, Op. 116 (learning to play it at the moment), Debussy's Syrinx and his Prelude A L'Apres-Midi dun Faune, Saint-Saens' Carnival of the Animals, etc etc.
