Two versions of this very popular 9th chord are illustrated in the diagrams. The C9 is a powerful and valuable chord.

Powerful because it fills out and enhances the basic "Blues" progression. Valuable because it is movable up the guitar fingerboard. Simply moving the C9 chord up two frets produces the D9 chord.

We suggest that you learn and utilize both forms. You select the appropriate form - the form that will best fit the chord accompaniment and or the melody.
