Gmaj9 Guitar Chord
Gmaj9 is the G major ninth chord. It has five notes: G, B, D, F♯ and A. The open shape takes two fingers, one on each outside string, and the four strings between them ring open.

Middle finger on the low E at the 3rd fret, index on the high E at the 2nd, with four open strings between them.
How to play Gmaj9, step by step
- Middle finger: 3rd fret, low E string
- Index finger: 2nd fret, high E string
- Let the A, D, G and B strings ring open.
- Strum all six strings.
The same two finger idea as G9, with the high E one fret higher. Sliding that finger between the 1st and 2nd fret switches the chord between G9 and Gmaj9.

If the barre is uneven
- Strings under the barre drop out
- Roll the index onto its outer edge so the bone holds the strings, and keep it just behind the 3rd fret.
- The two strings under the middle finger are uneven
- It covers the D and G strings at the 4th fret. Lay it flat and check both notes ring.
- The chord sounds thick
- Five notes on six strings is dense. Strum lightly and let the top of the chord speak rather than digging into the bass.
What makes it a Gmaj9
G · B · D · F♯ · A 1 3 5 7 9
Gmaj9 is a Gmaj7 chord with a ninth added: G, B, D and F sharp make Gmaj7, and the A on top makes it a ninth.
It is the I chord of G major and the IV of D, two keys guitarists live in, so this is one of the more useful major ninths to know. The F sharp sits a half step under the root and the A a whole step above it, and that pair is what makes the chord float instead of settle.
Gmaj9 vs Gadd9
Gadd9 is G major with an A added and no seventh: bright, strummed, and common in folk and rock. Gmaj9 keeps the A and adds the F sharp as well, and the seventh is what turns it into a jazz chord.
In practice they are used in different music rather than as alternatives. Gadd9 opens a strummed song; Gmaj9 ends a quiet one.
