About
The F♯9 dominant ninth (F♯–A♯–C♯–E–G♯) extends a dominant 7 with a ninth. The G♯ adds brightness and harmonic richness without affecting the chord’s dominant function — the tritone between A♯ and E is still present and still drives resolution to B. The 3rd and ♭7 remain essential; the 5th is routinely dropped on guitar to make room for the 9th without creating a muddy cluster. Common in funk, jazz, and blues as a more colorful version of the dominant 7. Compared to F♯7, the 9th adds shimmer and modernity; the resolution tendency is identical.
