Minor-Major Seventh (minMaj7) Guitar Chord Diagrams and Theory

What are Minor Major 7 Chords ?

Minor major seventh guitar chords are built by adding a major seventh (7) to a minor triad (1-b3-5) thus giving this formula : root (1), minor third (b3), fifth (5) and major seventh (7). You can also think them as minor 7th chords with a major seventh in place of the minor seventh (b7).

Minor/major 7 chords are dissonant and unstable, they occur naturally when you harmonized the first degree of the harmonic minor scale and the melodic minor scale.
