Allchopin, from your previous posts, I gather that you judge the difficulty of pieces based on technical difficulties alone. Sure, Revolutionary Etude is obviously technically more difficult than Kinderszenen, but how about musically wise ?. And your analogy of comparing music to cars are rather flawed , sure people may be impressed with Ferrari driving down the road at breakneck speed, but is music all about show-offs and adrenalie rushes. Sure, to non musical people, a poorly played Chopin Ballade will defiinitely sound more impressive to them than a Mozart Sonata played very well musically. That's what pop culture is about nowadays, all flash and no substance. Sure, the public like it, but is that true art, NO!!!!! In the end Allchopin, playing piano music is not about impressing others or satisfying your own ego, its about making the best music you can for others. I guess you have never performed for musicians before, but I did last time when I was still self-taught, and guess what, what I thought was wonderful was revolting to them. Anyway, in the end, strive to make the best music you can, do justice for the composers.
And you mention about going to college to study music. Good luck to you, though it may well be extremely difficult for you since you may not be aware of your deficiencies, and most colleges they will only accept students with good foundations. And I never met a pianist that have good foundations without a teacher.
