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 9 chord tones across standard tuning.
This same arpeggio shape is also commonly called F# Major Ninth or F#Maj9.
Chord construction and defining tones
F# major 9 is defined by 3 (A#), 7 (E#), and 9 (G#). It extends a major seventh chord with the ninth while retaining the natural seventh.
Harmonic use
Use this arpeggio over F#maj9 and spacious tonic-major or major-seventh harmony that includes the ninth.
Practice this arpeggio on guitar
- Play the F# Major 9 arpeggio from one F# root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Practice 3 (A#), 7 (E#), and 9 (G#) as the upper structure, then reconnect them to the root and fifth.
- Improvise over F#maj9 and alternate resolutions from the ninth to the root with resolutions from the seventh to the root.
