About
The F♯6 chord (F♯–A♯–C♯–D♯) adds the major sixth to a major triad. The sixth is a stable, consonant addition — it does not introduce dissonance the way a 7th does — which gives 6 chords a warm, slightly vintage sound common in jazz, swing, and older pop. They can substitute for F♯ or F♯Maj7 as tonic harmony when a less tense color is wanted. The D♯ is the defining extension; the 5th can be omitted. On guitar, 6-chord voicings tend to be compact and practical for comping. Compared to F♯Maj7, the 6 feels more grounded and less harmonically ambiguous — the 6th sits further from the root than the 7th does, so it creates no half-step tension.
