Chord Detail
G Major Triad
G is a G major triad — one of the most fundamental chords in music. Formed by stacking a major third and a perfect fifth above the root, it provides the bright, stable foundation at the heart of countless songs.
The major triad is built by stacking two intervals above the root: a major third (4 semitones) and then a minor third (3 semitones) above that, producing a perfect fifth (7 semitones from the root). G uses the notes G, B, D. The major third (B) gives the chord its bright, "happy" quality — this is the interval that separates major from minor. The perfect fifth (D) grounds and stabilizes the sound. In harmony, a major chord typically acts as a point of rest or resolution, especially when it is the tonic (I) chord in a key.

Major chords are the bright foundation of Western harmony — stable, resolved, and immediately recognizable. Their structure (root, major third, perfect fifth) creates a sound that feels complete and confident, like a musical declaration of "yes."
