How to read this arpeggio
The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent F# root notes, while circular markers represent the remaining tones in the arpeggio.
Use the interactive fretboard to locate the F# root notes and connect the remaining major add9 chord tones across standard tuning.
This same arpeggio shape is also commonly called F# Major Add 9 or F#Add9 or F#Add2.
Chord construction and defining tones
F# major add9 is defined by 3 (A#) and 9 (G#). It keeps the complete major triad and adds the ninth without including a seventh.
Harmonic use
Use this arpeggio over F#add9 and major chords where the ninth adds color but no major- or dominant-seventh quality is intended.
Practice this arpeggio on guitar
- Play the F# Major Add9 arpeggio from one F# root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Pair 3 (A#) and 9 (G#) in different octaves and keep the ninth separated from the root when possible.
- Outline F#add9 and use the ninth as a melodic upper extension before returning to the triad.
