The standard grips this chord is usually shown with.
Dmaj7 is D, F#, A and C# — D with the major seventh added on top.
It sounds lush, and only just resolved. The everyday tonic of jazz, bossa and neo-soul.

| D | F# | A | C# |
|---|---|---|---|
| 1 | 3 | 5 | 7 |
Tonic — a resting chord, but a soft one.
Also written DM7, DΔ7, DΔ, Dma7 or D major 7. The same chord either way; which spelling you meet depends on who wrote the chart.
Dmaj7 in 2nd inversion puts A in the bass instead of D, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
One of Dmaj7’s 8 common shapes does this: xx7779.

How you get to it. The turn that lands on Dmaj7 is Em7 to A7 — the ii and the V of D — and A7 shares its third and seventh with Em7, so the hand barely moves between them.
