Hi! I'm a new member! I am also learning Claire de Lune. The 9th bar to the end is not so difficult if you have a constant training. The secret is, I use 2 hands for the left hand. Actually, when you ignore the left hand, there are very few to play. So, I use two hands. But let me tell you, 1the hardest part of the song is the 16th bar. It confuses me a lot. FYI, I have been studying this song 4 years. Still struggling in the 16th bar. OK, good luck!
