This is a reworking of three 17th-century dance tunes. One of the great things about living in this modern age is that we have auditory access to centuries of musical styles. If I wish, I can take these old folk tunes, and infuse them with some early German romanticism, some French impressionism, some Soviet dissonance, and maybe even some power-chords. That's exactly what I did here.
The lyrics halfway through are a verse from "I'll never love Thee more", by James Graham, Marquis of Montrose.
