Bb Aeolian scale on the guitar fretboard

The Bb Aeolian scale is made of Bb (the root), C (major second), Db (minor third), Eb (perfect fourth), F (perfect fifth), Gb (minor sixth) and Ab (minor seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the scale.

The Aeolian mode is the natural minor scale, the sixth mode of the major scale. It shares its notes with the major scale a minor third above, so the neck shows one shape with two names. Its close relatives are the harmonic and melodic minor scales.
