The diagrams below show all of the dominant ninth chords. (Such chords are usually just called ninth or 9th chords.) Use notes 1 - 3 - 5 - b7 - 9 in a particular key to create the chords. For an explanation of the figures, go to the notation file. To understand how the chords are derived, go to the tutorial on keys. Table 3 is a quick summary of how chords are formed, and Table 2 contains all the notes in all of the (major) keys.
Both Ab9 forms, one of the Bb9 forms, and a few other forms can be moved along the guitar's neck. The principles are explained further in the Bar Chords section.
