Dm7

Dm7, short for D minor seventh, is a four-note chord in which a minor triad on D is extended with a minor seventh. It consists of the notes D, F, A, and C. The interval structure is a minor third from D to F, a perfect fifth from D to A, and a minor seventh from D to C. In notation, it is written as Dm7.

As a harmony, Dm7 is a diatonic seventh chord. In major keys, it is the ii7 chord (for example, in C major the notes D-F-A-C form the ii7). In the key of D minor, Dm7 can function as the i7 (D-F-A-C). It often serves as a predominant in chord progressions, typically resolving to a dominant (for example, Dm7–G7–C).

Common voicings include the guitar shapes xx0211 (D-F-A-C over strings 4–1) or x x 0 2 1 1, both spelling D-F-A-C. On piano, a basic arrangement is D in the left hand with F–A–C in the right hand. Extensions such as Dm9 (adding E) or Dm11 (adding G) are used to color the harmony. The chord is widely used in jazz, pop, and funk, and figures prominently in ii-V-I progressions across keys.
