Moonlight Sonata "Third movement"Chopin Ballade in g minorChopin Scherzo No.2Maybe an etude?-I've already worked on all of the above, just not to mastery yet. But since I'm taking a class (finalyl getting a teacher after 3 years) maybe I would use one of these to perfect it.Chopin's Nocturne (one of em?)Ravel's PavaneWhich two pieces would be the easiest to learn in a 9 week period?
