Dm6

Dm6 is a four-note chord in music theory, built on the root D. It consists of the notes D, F, A, and B, forming a D minor triad (D–F–A) with an added major sixth above the root (B). In interval terms, it contains a minor third, a perfect fifth, and a major sixth above D.

Voicings for Dm6 vary by instrument. Common spellings include D–F–A–B, with inversions such as F–A–B–D or A–B–D–F. Depending on context, players may omit one of the outer voices or substitute nearby tones, and some arrangements use richer extensions such as D–F–A–B–E in a Dm6/9 voicing.

Usage and function: Dm6 is often treated as a coloristic variant of the ii chord in major keys and is widely used in jazz, pop, and fusion. A typical progression in C major is Dm6 → G7 → C, where the Dm6 provides a smooth bridge to the dominant. It can also function as a substitute for Dm7 in certain contexts, offering a brighter, more ambiguous color due to the raised sixth.

Relation to theory: Dm6 can be viewed as Dm7 with the seventh (C) replaced by the sixth (B). While B is not part of the natural D natural minor scale, the major sixth is a common extension in tonal harmony, contributing a distinct, lush color when moving to cadences or neighboring chords.
