Chords in D major
D major is built from the notes D, E, F#, G, A, B and C#. Its scale carries 2 sharps. Harmonising that scale in thirds gives seven chords — 3 majors, 3 minors and 1 diminished — starting on D as the I. The chord on the fifth degree is A, a major V, so D major has the leading tone that makes a A-to-D cadence sound final.
Beyond those seven, D major commonly borrows Dm (i), Edim (iiø), F (bIII), Gm (iv) and Am (v) from the parallel minor — the mixture chords that give a progression somewhere unexpected to go.
The seven chords
Extended to four notes each, the same seven degrees give Dmaj7, Em7, F#m7, Gmaj7, A7, Bm7, C#m7b5.
