G9 is G, B, D, F and A.
G9 has five notes, and the bass has four strings to play them on. The rest of this page shows how a hand fits one to the other.
On the staff
On a bass staff, G9 is written G, B, D, F and A.
The staff shows the notes one after the other, then together. Written this way the chord is in close position, which means each note sits as near to the one below it as the spelling allows. A guitar almost never plays a chord in close position.
G9 under a hand
Strummed from the lowest string to the highest, this grip sounds G, B, F and G, which are the degrees 1 3 ♭7 1 rather than the 1 3 5 ♭7 2 of the written chord. The root is the lowest note, so this grip is in root position and sounds the way the written chord suggests. With G in the bass and four strings sounding five notes, the 1 appears more than once. The 5 and 9 is left out altogether. A seventh chord gives up its fifth first, because the fifth adds the least to the chord's sound.
Strummed from the lowest string to the highest, this grip sounds B, F, G and D, which are the degrees 3 ♭7 1 5 rather than the 1 3 5 ♭7 2 of the written chord. The lowest note is the 3 rather than the root, so this grip is in first inversion, written G9/B. It has the same notes as the root-position grip, but with B in the bass it sounds different. The 9 is left out altogether. A seventh chord gives up its fifth first, because the fifth adds the least to the chord's sound.
Strummed from the lowest string to the highest, this grip sounds D, G, B and F, which are the degrees 5 1 3 ♭7 rather than the 1 3 5 ♭7 2 of the written chord. The lowest note is the 5 rather than the root, so this grip is in second inversion, written G9/D. It has the same notes as the root-position grip, but with D in the bass it sounds different. The 9 is left out altogether. A seventh chord gives up its fifth first, because the fifth adds the least to the chord's sound.
Strummed from the lowest string to the highest, this grip sounds F, B, D and G, which are the degrees ♭7 3 5 1 rather than the 1 3 5 ♭7 2 of the written chord. The lowest note is the ♭7 rather than the root, so this grip is in third inversion, written G9/F. It has the same notes as the root-position grip, but with F in the bass it sounds different. The 9 is left out altogether. A seventh chord gives up its fifth first, because the fifth adds the least to the chord's sound.
Four shapes for G9 on bass: G9, G9/B, G9/D and G9/F.
Every grip here is G9, but no two of them sound alike. A chord with the root as its lowest note is in root position, and a chord with any other note at the bottom is an inversion. On a keyboard you choose the inversion you want, but on a neck the shape your hand can reach usually decides it for you. When a grip sounds a note more than once, the fretting hand decides which note that is, not the harmony.
G, B, D, F and A on the whole neck
This diagram marks every G, B, D, F and A on the first fifteen frets of the bass.
Every grip above is a handful of the notes on this diagram, and none of them uses a note that is not shown here.
Where G9 comes from
G9 is a chord of C major and A natural minor.
A chord does not belong to a single key. Each major or natural minor key listed here contains every note of G9, which is why the same grip turns up in songs that otherwise have little in common.
