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 major add9 chord tones across standard tuning.

This same arpeggio shape is also commonly called G Major Add 9 or GAdd9 or GAdd2.

Chord construction and defining tones

3B
9A

G major add9 is defined by 3 (B) and 9 (A). It keeps the complete major triad and adds the ninth without including a seventh.

Harmonic use

Use this arpeggio over Gadd9 and major chords where the ninth adds color but no major- or dominant-seventh quality is intended.

Practice this arpeggio on guitar

  1. Play the G Major Add9 arpeggio from one G root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
  2. Pair 3 (B) and 9 (A) in different octaves and keep the ninth separated from the root when possible.
  3. Outline Gadd9 and use the ninth as a melodic upper extension before returning to the triad.
