A '''minor seventh chord''' is a [[tetrad]] comprising a root, a [[minor]] third, a [[perfect]] fifth, and a minor seventh. | |||
== In just intonation == | |||
In the [[7-limit]]: | |||
* [[12:14:18:21]], the ''subminor seventh chord'', is a [[9-odd-limit]] chord that tunes both the third and the seventh flatter than the 5-limit minor. | |||
In the [[5-limit]]: | |||
* [[10:12:15:18]] is found on the iii ({{Frac|5|4}}) and vi ({{Frac|5|3}}) of Ptolemy's intense diatonic scale ([[Zarlino]]), perhaps the most common 5-limit diatonic. | |||
* [[27:32:40:48]] is found on the ii ({{Frac|9|8}}) of Ptolemy's intense diatonic scale. | |||
In the [[3-limit]]: | |||
* [[54:64:81:96]] is found on the ii ({{Frac|9|8}}), iii ({{Frac|81|64}}), and vi ({{Frac|27|16}}) of the Pythagorean diatonic scale, and may be considered a 3-limit approximation of both 10:12:15:18 and 27:32:40:48. | |||
