A minor major seventh chord, or minor/major seventh chord About this sound play (help·info) (written as mM7, mΔ7, -Δ7, mM7, m/M7, m(M7), minmaj7, m⑦, etc.) is a naturally occurring diatonic nondominant seventh chord in the harmonic minor scale. The chord is built on a root, and above that the intervals of a minor third, a major third above that note and above that a major third (see infobox). It can also be viewed as taking a minor triad and adding a major seventh. The traditional numerical notation is based on the degrees of the major diatonic scale, and by this notation a minor major seventh chord is degrees 1, ♭3, 5, 7 of the major scale. For instance, the CmM7 chord consists of the notes C, E♭, G, and B. The chord can be represented by the integer notation {0, 3, 7, 11}.
