The D Major Seventh chord contains D, F♯, A, C♯. Formula: 1–3–5–7.
A d major seventh is a major triad plus a major seventh.
Preserve the written chord spelling shown here; keyboard equivalence does not rename the chord.
Choose a position to keep the four written notes, sounding keys, bass note, playback and print reference synchronized.
Dmaj7 uses 1–3–5–7: D–F♯–A–C♯.
a major triad plus a major seventh
Compared with D major, add the major seventh above the root.
A seventh chord has four chord tones and therefore four positions: root position plus three inversions. The slash symbol identifies the written bass note.
| Position | Symbol | Notes, low to high | Bass |
|---|---|---|---|
| Root position, current selection | Dmaj7 | D4–F♯4–A4–C♯5 | D4 |
| First inversion | Dmaj7/F♯ | F♯4–A4–C♯5–D5 | F♯4 |
| Second inversion | Dmaj7/A | A4–C♯5–D5–F♯5 | A4 |
| Third inversion | Dmaj7/C♯ | C♯5–D5–F♯5–A5 | C♯5 |
