Temperament calculator

[under development]

Boxes between pitch classes in the list below should be filled with adjustments to the perfect fifth to either fit the circle-of-fifths better to twelve tones (such as by flattening all fifths by 1/12 of a Pythagorean comma to create equal temperament) or to adjust major thirds closer to a 5/4 ratio. A value -1/4s means to flatten the fifth between the two adjacent notes by 1/4 of a syntonic comma (81/80 ratio). The value -1/4p is 1/4 of a Pythagorean comma (3^12/2^19 ratio).
