Module:Ups and downs sharpness

Module documentation[view] [edit] [history] [purge]

This module should not be invoked directly; use its corresponding template instead: Template:Ups and downs sharpness.

This module automatically creates a table with the combinations of symbols to notate a given edo using Kite's ups and downs notation.
