9th chords

The 9th chord is frequently used in styles like funk and jazz. The chord is constructed by adding the ninth note in the scale to a dominant 7th chord. The C9 for example, includes the following notes: C, E, G, Bb and D.

The diagrams show the 9th chords in movable versions. Adapting to these versions makes the chord really simple to memorize.

To play the chord you have to lay your ring finger over the three highest strings (see picture to the right). It is also possible to skip the high E-string (i.e. the 1st string), and in that case you can instead use all four fingers. If you leave out the high E-string, you will not play the fifth, but it is alright to omit that note in a 9th chord.

Chord progressions

If you know how to play a 12 Bar Blues chord progression you can mix it up by replacing the IV7 and V7 with IV9 and V9. In other words, a 12 Bar Blues progression could look something like:

A7 – D9 – A7 – E9 – D9 – A7

9th chord voicings without the root

An easier way to play these chords is to remove the tone on the 5th string. This turns the chord into a voicing without the root note and, for example, C9 will be played XX2333 and F9 will be played as XX7888.

9th chords with bass note on 6th string

To be more flexible, you could learn a shape with its base tone on another strings. This shape is using the 6th string for the bass and root note.

G9: 3X320X
Ab9: 4X431X
A9: 5X5412X
Bb9: 6X653X
B9: 7X764X

9th chords with bass note on 4th string

Here is a third alternative, which use the 4th string for the bass and with the root note on the 1st string.

G9: XX3203
Ab9: XX4314
A9: XX5425
Bb9: XX6536
B9: XX7647

9th sus chords

It is also possible to play ninth suspended chords. A movable shape similar to that presented above can be used, here are some examples in notated form:

B9sus: X22222
C9sus: X33333
D9sus: X55555
E9sus: X77777
F9sus: X88888

Notice that 9sus are identical to one version of the 11th chord.

9th chord alterations

Alterations means that a note in the chord is altered, for example, a flattened fifth. Here are some examples using C as root tone (the shapes are movable)

C9+5: X32334
C9b5: X32332

We can compare these alterations with the standard dominant ninth:
