Have you ever litstened to a classical peice without knowing what it is and you automaticly go "Hey! That's totally Beethoven's work" or "That just SCREAMS Rachmaninoff in your face!!" So... what is it about their music that makes it so you can tell it apart so well? (if you can)
For me, I can tell it's beethoven when it's played in a minor key, then all the sudden it just starts sounding like.... beethoven. It's hard to explain, but the styles that I can recognize are those of Chopin, Rachmaninoff, Liszt, Beethoven, and somtimes Tchaikovsky and Medtner.
