Min/Maj 7 Chords

The min/maj7 chord is a minor triad (1stb3rd, 5th) with a major 7th added on top. So it is kind of the opposite of a dominant 7, which is a major triad with a minor 7th on top.

The min/maj 7th chord can be used as a root chord in minor harmonies and is derived from the harmonic minor scale (which contains the sharp 7th).

See Harmonizing the Minor Scale for more information.
