User talk:Frostburn/Music vs Math
I suggest:
algebraic variety (solutions of a system of equations over a vector space (roughly, I don't want to go too far into algebraic geometry)) and scale variety (how many different interval sizes are there for the same step difference);
don't forget
limit (of a sequence, function, category, etc.) and (prime/integer/odd) limit
Also note the amusing "return" of etymology, in comma category:
A comma in tuning and also in punctuation comes from the Greek root word κόπτω, meaning "cut"
The sense of the punctuation was used for denoting a comma category because the notation uses a comma
But then people renamed it to "slice category".
Cut and slice. How poetic
