Contributor Just Another Brony shared a very cool version of So Many Wonders. It's sheet music for the bass line of the song with a fun swing rhythm. Check it out in either MuseScore or PDF. (If you don't have MuseScore, you can download it here for free.)
Just Another Brony suggested that it might be a cool project to build on this bass line. Have fun!
Thanks again to Just Another Brony for sharing so many resources for this song.
