Eb Mixolydian scale on the guitar fretboard

The Eb Mixolydian scale is made of Eb (the root), F (major second), G (major third), Ab (perfect fourth), Bb (perfect fifth), C (major sixth) and Db (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 Mixolydian mode is a major scale with a lowered seventh, the fifth mode of the major scale. It shares its notes with a major scale a fifth below, so one set of positions serves both. It is the scale that fits the dominant seventh chord.
