D Minor Major Seventh chord (Dmmaj7) on the guitar fretboard

The D Minor Major Seventh chord (Dmmaj7) is made of D (the root), F (minor third), A (perfect fifth) and C# (major seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

The minor major seventh joins a minor triad to a major seventh, an unusual pairing of a dark middle and a bright top. Its four notes repeat across the neck like any other seventh chord, with the root and seventh sitting a semitone apart. Lower the seventh by a semitone and you are back at the minor seventh.
