Hints of Theory

A bit of an emergency blip but this has been lurking for such an occasion.  Unearthed this in one of the basement sort-outs.  I assumed it was one of the Cheeseminors' but it seems to have my name on top.

Curiously, I seem to have retained more* musical theory knowledge than I have memory of ever having been taught any.

* i.e. a very slightly non-zero quantity.
