Rodan comma: Difference between revisions

The rodan comma (monzo: [20 -17 3⟩, ratio: 131072000/129140163), otherwise known as the roda, is a small 5-limit comma of about 25.7 cents. As part of the syntonic–diatonic equivalence continuum, it is the difference between the Pythagorean diatonic semitone (256/243) and a stack of three syntonic commas. It is also the amount by which a stack of three acute whole tones (729/640) falls short of the perfect fifth.
