Hi Pianostreet,
I'm a piano student who's now starting to play pieces at a Grade 10 RCM level. I'm also a big Debussy fan!

I just finished "Minstrels" from the Preludes Book 1, and I'm on to my next Debussy piece. I'm thinking of either playing the very famous Arabesque no. 1, or the less famous but still equally beautiful, Doctor gradus ad Parnassum from
Children's Corner. They are both listed as Grade 10 pieces for RCM.
Arabesque no. 1 is a very nice piece and I'm quite familiar with it because I've been listening to it since I was 6 (I'm 14 now) from our electronic yamaha piano. It's twice as long as Doctor gradus ad Parnassum (6 pages compared to 3), so I'm thinking that it would keep me entertained longer, since my teacher will probably only let me do one more Debussy piece this year.
I just picked up on Doctor gradus ad Parnassum and I think it would be a nice choice since it's an easier Grade 10 piece and it is very nice, but it is so short and even though I would enjoy every moment of playing it, I think I would complete it in a shorter amount of time, and then no more Debussy until September 2016.
What are your guys opinions on these pieces? I want to know what you guys think about them and what you think I should play.
If you don't know what Doctor gradus ad Parnassum sounds like, here's the youtube video:
Thank you!
