This is my interpretation of Pyotr Tchaikovsky's "Dance of the Little Swans" from his ballet Swan Lake (to wit No. 13 Pt. IV). That is, I made it into a Hardstep (i.e. "wubless dubstep") track in Famitracker, and the end result, when I finally release it on an album, can be played back on an NES which is modded to play the VRC6 expansion soundchip as heard in the Japanese version of Castlevania 3 (which they call "Akumajou Densetsu" which translates to "The Legend of the Devil's Castle").
