'''6561/5120''', the '''retroptolemaic major third''', is a [[5-limit]] [[interval]] measuring about 429.32{{cent}}. It is equal to the Pythagorean major third of [[81/64]] ''raised'' by a syntonic comma ([[81/80]]), compared to the just major third [[5/4]] which is the Pythagorean interval ''lowered'' by the syntonic comma. It differs from [[41/32]], the 41st harmonic, by the unnoticeable comma [[6561/6560]]. | '''6561/5120''', the '''retroptolemaic major third''', is a [[5-limit]] [[interval]] measuring about 429.32{{cent}}.
