Hello flying fingered friends: With not a little effort I have gotten Chopin's preludes 4, 6, 7, 15 and 20 pretty well learned. In terms of technical difficulty what prelude should be next? (I guess #2 in Am might be next but after reading what seems to be rather universal disdain for it, I am open to skipping it.) Should I look at a nocturne, waltz, mazurka, or his cantabile instead? I've already tackled Mazurka in Gm op 67 #2, Nocturne in Cm op post #21 and I'm almost done with his Waltz in Am op post. My goal is to develop as large a Chopin repertoire as possible while becoming more and more proficient at the instrument. I hope that each piece will help me develop technically. As far as the "musical" difficulty, I am very satisfied with something that will take me a lifetime... That's what's so great about Chopin! Thanks!
