How to read this arpeggio
The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent A root notes, while circular markers represent the remaining tones in the arpeggio.
Use the interactive fretboard to locate the A root notes and connect the remaining minor chord tones across standard tuning.
This same arpeggio shape is also commonly called A Minor Triad.
Chord construction and defining tones
A minor combines b3 (C) and 5 (E). The minor third establishes the minor quality, while the perfect fifth keeps the triad grounded.
Harmonic use
Use this arpeggio to outline Am and other minor chords without adding seventh- or ninth-chord color.
Practice this arpeggio on guitar
- Play the A Minor arpeggio from one A root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Move between the root and b3 (C) and 5 (E), giving extra attention to the minor third that identifies the chord quality.
- Improvise compact phrases over Am and finish each phrase on the root, minor third, or fifth.
