About

The G major triad (G–B–D) is built from a root, major third, and perfect fifth. Its stability comes from the perfect fifth — the strongest consonant interval — anchored by the major third that gives it its bright, open character. It serves as the tonal center (I chord) in G major and the target of resolution from the dominant. Common moves include G–C–D (I–IV–V) and the D7–G cadence (V–I) that defines tonal music. On guitar, the fifth can be doubled or omitted in dense voicings without losing identity, but the major third (B) is indispensable — it is the one note distinguishing major from minor and from a power chord. Compared to Gm, the raised third is the entire difference in color.
