To all Piano/Classical music enthusiasts

[Reef]

I really need a recommendation for the next classical piano song I should learn to play.

Brief background: I started fiddling on the piano around age 10. I had no formal instruction-just read the level 1 books. Kept playing recreationally until H.S. freshman year where I took lessons. Dropped them as a junior due to financial reasons. Since then (about 5 years), I haven't really learned anything new and only play once a month. I'd like to get back into it minimally.

The song obviously needs to be awesome. As for difficulty, it can range between fuer elise/moonlight sonata to book level 6 difficulty (Bach - Solfeggio).

thanks
