The [[5-limit]] [[superparticular]] interval '''16/15''' is the '''just diatonic semitone''', '''classic(al) diatonic semitone''' or '''ptolemaic diatonic semitone'''<ref>For reference, see [[5-limit]]. </ref> – the difference between the major third [[5/4]] and the fourth [[4/3]]~~, and between~~ [[3/2]] and [[8/5]].

The [[5-limit]] [[superparticular]] interval '''16/15''' is the '''just diatonic semitone''', '''classic(al) diatonic semitone''' or '''ptolemaic diatonic semitone'''<ref>For reference, see [[5-limit]]. </ref>.

It is the difference between:

* the major second [[9/8]] and the minor third [[6/5]];

* the major third [[5/4]] and the fourth [[4/3]];

* the perfect fifth [[3/2]] and the minor sixth [[8/5]];

* the major sixth [[5/3]] and the minor seventh [[16/9]];

* the major seventh [[15/8]] and the perfect octave [[2/1]].

== Approximation ==

16/15 is very accurately approximated by [[43edo]] (4\43).

== Temperaments ==

When this ratio is taken as a [[comma]] to be [[tempering out|tempered out]], it produces [[father]] temperament, and lends itself the name '''father comma'''. In this [[exotemperament]], 4/3 and 5/4 are equated, and major thirds and fifths become [[octave complement]]s of each other. It is a [[Mersenne comma]].

The following [[linear temperament]]s are [[generate]]d by a [[~]]16/15:

* [[Vavoom]]

* [[Stockhausenic]]

In addition, this [[fractional-octave temperaments]] are generated by a ~16/15:

* [[Quintosec]]

Some [[11th-octave temperaments]] treat ~16/15 as the period, including [[hendecatonic]].
