Original Wikitext content:
The undecimal augmented fourth, or 15/11, is the difference between the 11th and 15th partials of the [[OverToneSeries|harmonic series]]. It is 536.95 [[cent|cents]] wide, exactly [[45_44|45/44]] larger than a perfect fourth, and almost exactly a sixth-tone sharper than a [[12edo|12-edo]] fourth. It is narrower than [[11_8|11/8]] by exactly [[121_10|121/120]]. 15/11 can be called a [[superfourth]], as it falls between the [[interval category|interval categories]] of a [[perfect fourth]] and a [[tritone]]. 4 steps of [[9edo|9-edo ]] is an excellent approximation for 15/11.
