A minor-major seventh chord is a tetrad comprising a root, minor third, perfect fifth, and major seventh.
In temperaments
The minor-major seventh chord is a 15-odd-limit essentially tempered chord in marvel and thus in septimal meantone, for which the historically prevalent quarter-comma meantone is a good tuning, with the augmented fifth between the third and the seventh being 75/48, tempered together with 14/9.
- (Marvel) 1–6/5–3/2–15/8
In just intonation
In the 5-limit:
- 40:48:60:75 is found on the I (1⁄1), IV (4⁄3), and V (3⁄2) of the duodene.
In the 3-limit:
- 3456:4096:5184:6561 spans eight octave-reduced fifths, and may be considered a 3-limit approximation of 40:48:60:75.
