I know a lot of classical (by the broad definition of the term) piano music.
Rachmaninoff Prelude in C# Minor (Granted, it's not the happiest piece, but it sounds lovely.)
Turkish March
Cohen Scherzo #7 (Okay, this was technically made in the 2000's, but it sounds classical.)
I'd add more but I just had a brainfart.
Youtube is also a great resource for this.
