Add9 chords

The add9 chord is a major chord with the ninth tone in the scale added. If we take the C major chord as an example, it consists of C, E and G. If we add a D we have a Cadd9 chord with the notes C, E, G and D.

You must separate this chord from the Dominant ninths that are written like C9. The difference is that a dominant 9th is made by adding the ninth to a seventh chord, like C, E, G, Bb and D forms a C9. In an add9 chord the seventh is missing.
