How to use the fretboard explorer
- Choose a key and a scale (or a chord to see its arpeggio). Red dots are the root notes — your “home base”.
- Switch labels to “Intervals” to see the function of each note (1, ♭3, 5…). This is how pros think about the neck.
- Click any dot or fret to hear it, or press “Play scale”.
- Try alternate tunings to see how shapes move in Drop D or DADGAD.
