15/14 is a superparticular ratio with a numerator which is the fifth triangular number.
It may be found as the interval between many 7-limit ratios, including:
- 16/15 and 8/7
- 14/13 and 15/13
- 7/6 and 5/4
- 6/5 and 9/7
- 14/11 and 15/11
- 4/3 and 10/7
- 7/5 and 3/2
- 22/15 and 11/7
- 14/9 and 5/3
- 8/5 and 12/7
- 26/15 and 13/7
- 7/4 and 15/8
Although called "septimal diatonic semitone" for its proximity (and conflation in systems such as septimal meantone) with the classic diatonic semitone 16/15, 15/14 is a chromatic semitone in both Helmholtz-Ellis notation and Functional Just System because it is 5120/5103 larger than the apotome 2187/2048.
