Talk:Periodic scale
I'd like the page to mention the two ways of writing a periodic scale as a function:
- The cumulative form (the formalization on the article), a monotone increasing function such that S(0) = 0 (unison) and S(k len(S)) = kE where E is the equave.
- The step form, related to the above via ΔS(k) = S(k + 1) − S(k), which is nonnegative and periodic in the usual math sense.
