How the D major triad is built
Start on D, add a major third, then a perfect fifth. The result is D–F#–A; its formula is 1–3–5.
- Notes
- D–F#–A
- Interval formula
- 1–3–5
Where it is used
Major triads often establish a stable major-key center and supply the I, IV, and V chords of a major key. Their exact function still depends on the surrounding music.
Listen and play
Play D–F#–A one note at a time, then together. Sing the middle note, lower it by one semitone, and compare the major triad with its minor form.
Related chords and scales
Pitch-set containment follows the spelled source notes. Same-tonic connections use the Bridge heuristic, not a claim of functional compatibility.
