Chords in the Key of D Major
The key of D major contains seven diatonic chords built from the notes D, E, F#, G, A, B, and C#. With two sharps (F# and C#), D major has a bright, ringing quality that works beautifully on guitar — making it a favorite for folk, country, and rock songwriters.
The 7 Triads in D Major
When you harmonize the D major scale in thirds, you get these seven triads. Each chord is built by stacking every other note from the scale:
| Degree | Roman Numeral | Chord | Notes | Quality |
|---|---|---|---|---|
| 1st | I | D major | D – F# – A | Major |
| 2nd | ii | E minor | E – G – B | Minor |
| 3rd | iii | F# minor | F# – A – C# | Minor |
| 4th | IV | G major | G – B – D | Major |
| 5th | V | A major | A – C# – E | Major |
| 6th | vi | B minor | B – D – F# | Minor |
| 7th | vii° | C# diminished | C# – E – G | Diminished |
Notice the pattern: Major – minor – minor – Major – Major – minor – diminished. This pattern is the same for every major key — only the root notes change. You can explore this pattern for any key using the D major scale harmonizer.
Seventh Chords in D Major
Adding a fourth note (the seventh) to each triad creates richer, more colorful chords. These are essential for jazz, R&B, neo-soul, and modern pop:

| ii | Em7 | E – G – B – D | Minor 7th |
| iii | F#m7 | F# – A – C# – E | Minor 7th |
| IV | Gmaj7 | G – B – D – F# | Major 7th |
| V | A7 | A – C# – E – G | Dominant 7th |
| vi | Bm7 | B – D – F# – A | Minor 7th |
| vii | C#m7b5 | C# – E – G – B | Half-diminished |
Common Chord Progressions in D Major
These are the most popular progressions composers use in D major. You can hear and explore all of them in our chord progressions library:
I – V – vi – IV (D – A – Bm – G)
The most used progression in pop music, transposed to D major. "Here Comes the Sun" (The Beatles) is a classic example in this key. The bright open D chord gives this progression an uplifting, sunny quality that matches the song's optimistic feel.
I – IV – V (D – G – A)
The foundation of blues, rock, and country music. In D major, all three chords are comfortable open shapes with a bright, ringing quality. "Free Fallin'" (Tom Petty) showcases how powerful this simple combination can be.
vi – IV – I – V (Bm – G – D – A)
Starting on the vi chord gives a minor-key flavor while staying in D major. The Bm barre chord adds a touch of tension that resolves beautifully through G and D back to A.

Tips for Composing in D Major
- Start with D, G, and A — these three open chords form the I-IV-V backbone and ring out with a bright, jangly character that defines the key.
- Use the relative minor — B minor shares the same notes as D major. Switching between D and Bm sections creates contrast without leaving the key.
- Add seventh chords to create sophistication. Replacing D with Dmaj7 or Bm with Bm7 instantly adds a jazzy or dreamy quality.
- Take advantage of the open D string — it serves as a drone note that reinforces the tonic, giving D major compositions a rich, resonant foundation.
- Explore arpeggios for melodic ideas. Playing the notes of each chord individually is a powerful way to create melodies that follow the harmony.
