Try entering one of your most unique melodies and hit search! Interesting stuff. I think it illustrates how important rhythm is for making something appear new. My best result so far is entering a sequence that only outputs 2 results from the database.
Edit: Just found one that matched none by entering something really funky lmao, I guess if it's less similar to classical you have a better chance. Or you can just enter something random as hell and it does the trick too lol.
