Grade 5 piano student playing in the University? Watch
Prelude VI: Des pas sur la neige (Footsteps in the snow)
It's a really effective piece, but not too hard once you get your head round the various layers to it. About grade 4 standard when you include all the dynamics and articulation.
You could also try Prelude VIII: La fille aux cheveux de lin (The girl with the flaxen hair), which is a bit harder, maybe grade 5/6 standard.
Here's the score for the book which the two preludes are in:
Debussy Preludes Book 1
@ Mods: Debussy died in 1918, so his music is out of copyright worldwide (the country with the longest period of copyright being Canada; 90 years after the death of the author), in case you were wondering whether it's legal to post his scores here.
I don't quite like Debussy's pieces..somehow haven't learned the way to appreciate it. I prefer Beethoven and Chopin's pieces(for romantic and classical) and Bach(my favourite composer, and what more, of my favourite type of music-Baroque!)
I'll check out the scores you provided.
