I love the piano. It's probably my favorite musical instrument. I love listening to people play. It puts me in a serene mood. What I want is this: I want your recommendations on the best songs in which piano is the dominant instrument. There are a couple stipulations.
1. No singing.
2. No brass accompaniment, though it can have strings.
3. Nothing upbeat
I'm basically looking for anything that resembles Moonlight Sonata. Something emotional, morose even. I'm not well versed in classical music, music at all for that matter. Any help that anyone can lend would be very appreciated.
