Hi guys,

I've been diligently studying the tuning-math archives, and
am really confused about one thing.

(OK, many things ... but let's start here...)

I'm having a really hard time understanding the differences
between "interval of equivalence", "period", and "unison-vector".

Why aren't they *all* unison-vectors?
