| Interval information |
245/243, the sensamagic comma, is a 7-limit interval of 14.2 cents. It is the amount by which two septimal major thirds (9/7) fall short of a classic major sixth (5/3), or the difference between 28/27 and 36/35.
Temperaments
Tempering it out leads to the sensamagic family of temperaments, where 5/3 is split into two equal parts, each representing 9/7~35/27, and may be extended to represent higher-limit ratios like 13/10, 22/17, etc. It enables sensamagic chords as well.
