Jacob: Thanks for the lead. I've never heard of single jigs before; I'll have to try to classify the 6/8 sheet music that I have and see which kind seems to fit the dances better.Anonymous: "Light" and "treble" might very well be specifically dance terms; the light jigs are done in soft leather slippers, and the treble jigs are done in hard shoes and use a step called trebling (tip-tap-down-tip-tap-down...).
My teacher said that a light jig might be played at around 150, and a treble jig around 75. I assume that means beats per minute, and that beat means quarter note.
I've never heard of a hop jig - I'll have to keep an eye out. Are they associated with any particular nationality? We also do 9/8 dances called slipjigs, that are always in soft slippers and are for girls only. I've been told that they don't have slipjigs in Scottish music.
