G9 Chord On The Guitar – Diagrams, Finger Positions and Theory

The G9 chord contains the notes G, B, D, F and A. It is produced by taking the 1 (root), 3, 5, b7 and 9 of the G Major scale. The 9th note of the scale (A) is the same as the 2nd note, but we refer to it as a 9, as this implies that the chord is a dominant 7 chord (1, 3, 5, 7) with a 9 included.

The 9th chord is a very popular guitar chord in Jazz, Funk and Blues. It is in many ways, the go-to ‘funk’ chord. The 9th chord can often be substituted for a dominant 7 chord. Let’s take an example chord progression:

Try playing this chord progression. After a while, try substituting the G7 chord for a G9 chord. You should hear that the chord progression sounds very similar, but the inclusion of the G9 chord gives the chord progression a jazzy sound.

The most common way to play G9 is with the root note on the 10th fret of the 5th string (second shape in the pic below).
