The '''26-comma''' is a [[3-limit]] [[semifourth]] that acts as a comma in certain temperaments. It is the difference between 26 perfect fifths and 15 octaves, as well as being two [[Pythagorean comma|Pythagorean commas]] sharp of [[9/8]].

While it is exceptionally large for a comma (two of them make a near-perfect fourth, off by the small [[53-comma]]), it is tempered out in [[26edo]], because of that temperament's narrow fifths.

As an ~~untempered~~ interval, it approximates intervals like [[15/13]], and is the simplest Pythagorean interval of this size. As such, it could also be known as ~~'''~~the''' Pythagorean semifourth.

Used as an interval in its own right, it is the '''Pythagorean inverse triple-diminished second'''. It approximates intervals like [[15/13]], and is the simplest Pythagorean interval of this size. As such, it could also be known as the ''Pythagorean semifourth''.
