Chopin by far! Ii'm just getting back into piano after a 20 year break. Well, I've been back into it for a year now. I've played Bach, Mozart, Beethoven, Clementi, and then finally Chopin! I LOVE CHOPIN. I'm on my third nocturne...the other stuff is too hard..plus i have a thing for the nocturnes!! It feels good to be where I'm at now...I will NEVER leave the piano again.....The funny thing is, I just took my daughter in to get her the piano lessons.. A month later, she was taking voice, and I was taking piano!!!
