About

The F♯ major 9th (F♯–A♯–C♯–E♯–G♯) extends a maj7 with a ninth. The result combines the gentle shimmer of the major-7 interval with the openness of the G♯. The 3rd, 7th, and 9th are the essential tones — the 5th is typically dropped on guitar, since it adds little harmonic information and clutters the voicing. Common in jazz and R&B as a tonic or subdominant color. Compared to F♯Maj7, maj9 feels more expansive and less static; the added 9th breathes air into the chord without introducing tension. Compared to F♯6/9, it is more harmonically active because of the 7th.
