About

The B major triad (B–D♯–F♯) 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 B major and the target of resolution from the dominant. Common moves include B–E–F♯ (I–IV–V) and the F♯7–B 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 (D♯) is indispensable — it is the one note distinguishing major from minor and from a power chord. Compared to Bm, the raised third is the entire difference in color.
