Dvorak Humoresque Op. 101 No. 7 for piano. Yes it's overplayed, yes it can be a bit schmaltzy, but it's a charming little piece, if a bit amateurishly payed.
Hey don't underestimate yourself. This is charming and one of the best versions on You Tube. I don't find it in the least overplayed .... in fact I'd suggest you watch a couple of clips of Lang Lang and really get into it. Throw your arms and body around a bit. As a student many years ago, I was repeatedly chastised for too much body movement. Now .... heck with Gould and Lang Lang, we're liberated. It's a fun piece! And your little furry audience is a delightful accent!
Delightful piece, delightfully played! Always a pleasure listening to you play. Keep up the good work. If you want to attempt something both schmaltzy and romantic, try Schubert's Fantasia in F. It's long and needs 4 hands, but I know you would do a great job with it.
