The notes in Gadd9
A added ninth chord is spelled from its root up: G (R), B (3), D (5), A (9). Those are the only notes in Gadd9 — play them in any order, in any octave, and it's still Gadd9.
What a added ninth chord is
In plain terms, an add9 keeps a full major chord and adds the ninth on top (root, 3rd, 5th, 9th) — colour without changing the chord's job.
How it's used: A major chord with sparkle: it stays a I or IV but shimmers. Unlike a sus, it keeps its third, so its major/minor identity is intact.
The sound: Bright, sparkling, modern — a major chord with extra light. Where you'll hear it: Modern pop, worship, acoustic singer-songwriter, ambient rock.
Hear Gadd9 in a progression
An add9 keeps its major job but sparkles — here in a I–V move. Press play, and drag the Key control to move it anywhere.
