F# Lydian scale on the guitar fretboard

The F# Lydian scale is made of F# (the root), G# (major second), A# (major third), B# (augmented fourth), C# (perfect fifth), D# (major sixth) and E# (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.
