The '''shallowtone comma''' or '''ptolemaic doubly-augmented unison''' (ratio: 295245/262144, monzo: {{monzo| -18 -10 1 }}) is an interval of 205.864 cents. It is equal to [[9/8]] raised by a [[schisma]] and is the difference between [[5/4]] and the Pythagorean diminished third [[65536/59049]]. It was named by [[User:CompactStar|CompactStar]] in 2024, referring to shallowtone being an [[2L 5s|antidiatonic]] counterpart of [[deeptone]], as well as it being just below the "surface" ([[5L 2s|diatonic]] fifths). | The '''shallowtone comma''' or '''ptolemaic doubly-augmented unison''' (ratio: 295245/262144, monzo: {{monzo| -18 -10 1 }}) is an interval of 205.864 cents.
