Eb Lydian scale on the guitar fretboard

The Eb Lydian scale is made of Eb (the root), F (major second), G (major third), A (augmented fourth), Bb (perfect fifth), C (major sixth) and D (major 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 Lydian mode is the fourth mode of the major scale, a major scale with a raised fourth. The raised fourth sits a tritone from the root, and the scale shares its notes with a major scale a fifth above. It is the brightest of the seven modes.
