What is a dominant 9 chord?

A dominant ninth is the combination of a dominant chord (with a minor seventh) and a major ninth. A major ninth chord (e.g., Cmaj⁹), as an extended chord, adds the major seventh along with the ninth to the major triad. Thus, a Cmaj⁹ consists of C E G B and D.

What notes are in a 9th chord?

Theoretically ninth chords are built with 5 notes called root (1), major third (3), perfect fifth (5), minor seventh (b7) and ninth (9). We will see that it is quite unusual to play these five notes together on the guitar.
