Well I played it for my grade 9 at RCM examinations in Canada, which I believe is about 8 in US? I'm not sure what it would be but same category as minute waltz, girl with the flaxen hair, ummmmmmmmmmmm Prelude Fugue in C minor, ummm June barcarolle by Tchaikovsky. Liebestraum is Grade 10, a level higher... I meant to say that it was extremely hard to memorize, not easy to memorize lol, but there are not any huge leaps, it's just a matter of putting left and right together... But you can't say it is extremely difficult.
