Division of 13/4 into equal parts does not necessarily imply directly using this interval as an [[equivalence]]. Many, though not all, ed13/4 scales have a perceptually important false octave, with various degrees of accuracy. | Division of 13/4 into equal parts does not necessarily imply directly using this interval as an [[equivalence]].

Equivalence aside, the structural significance of thirteenths like 13/4 is apparent by being the the top of the upper structure of jazz voicings, as well as a fairly trivial point to split the difference between the [[3/1|tritave]] and the [[4/1|double octave]]. | Equivalence aside, the structural significance of thirteenths like 13/4 is apparent by being the the top of the upper structure of jazz voicings, as well as a fairly trivial point to split the difference between the [[3/1|tritave]] and the [[4/1|double octave]]. | ||
