[[image:ji glyph 12 7.png width="136" height="120" caption="JI Glyph for 12/7 "]] **12/7** |-2 -1 0 1> 933.12909 cents [[media type="file" key="jid_12_7_pluck_adu_dr220.mp3" width="240" height="20"]] [[file:xenharmonic/jid_12_7_pluck_adu_dr220.mp3|sound sample]] In [[7-limit]] [[Just Intonation]], 12/7 is the septimal supermajor sixth of about 933.1¢. It represents the interval between the 12th and 7th harmonics and appears in chords such as 4:5:7:9:12. It differs from the 5-limit major sixth of [[5_3|5/3]] by [[36_35|36/25]] -- the septimal quartertone -- a [[superparticular]] interval of about 48.8¢. It differs from the Pythagorean major sixth of [[27_16|27/16]] by [[64_63|64/63]] -- Archytas' comma -- about 27.3¢. And finally, it differs from the harmonic seventh -- [[7_4|7/4]], about 968.8¢ -- by [[49_48|49/48]] -- the large septimal diesis or slendro diesis -- about 35.7¢. 12/7 is the inversion of the septimal subminor third of [[7_6|7/6]].
