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 major chord tones across standard tuning.
This same arpeggio shape is also commonly called A Major Triad.
