Harmonic Function

The D minor major seventh chord commonly functions as the supertonic (ii) in C major or dominant (V) in G major. Its harmonic role varies by key — in major keys it provides subdominant or supertonic color.

The minor-major seventh chord combines a minor triad with a major seventh, creating a uniquely tense sound. It appears in descending bass lines and is characteristic of film noir and jazz. The D Minor-Major Seventh Chord specifically contains 4 notes: D, F, A, C♯ (formula: 1-♭3-5-7). On guitar, D-rooted chords use the open D string as their bass note, and the compact open-D shape is one of the most recognizable chord voicings. Rock anthems and folk songs frequently center on D chords, which provide a bright, cutting tone that projects well in ensemble settings.
