How to read this arpeggio
The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent G root notes, while circular markers represent the remaining tones in the arpeggio.
Use the interactive fretboard to locate the G root notes and connect the remaining dominant 9 chord tones across standard tuning.
This same arpeggio shape is also commonly called G Dominant Ninth or G9.
Chord construction and defining tones
G dominant 9 is defined by 3 (B), b7 (F), and 9 (A). The dominant guide tones remain intact while the ninth adds an upper extension.
Harmonic use
Use this arpeggio over G9, dominant funk and blues harmony, or a V chord that includes the natural ninth.
Practice this arpeggio on guitar
- Play the G Dominant 9 arpeggio from one G root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Play 3 (B), b7 (F), and 9 (A) as a rootless three-note group in several positions, then add the root and fifth.
- Outline G9, emphasize the ninth, and resolve the third and flat seventh into the next chord.
