About
The D9 dominant ninth (D–F♯–A–C–E) extends a dominant 7 with a ninth. The E adds brightness and harmonic richness without affecting the chord’s dominant function — the tritone between F♯ and C is still present and still drives resolution to G. 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 D7, the 9th adds shimmer and modernity; the resolution tendency is identical.
