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