G Lydian on the Guitar Fretboard
The notes of Lydian repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.
- Frets 0–5 (span 5 frets)
- Lowest note G, highest note F#
- 2 G root notes, on the E string (fret 3), G string (fret 0)
How to practice this shape
- Start on the root — G at fret 3 on the E string. Play up to the highest note in the shape, then back down, staying inside frets 0–5.
- Your hand shifts 2 times as you cross strings: E→A (-1), D→G (-2). Those crossings — not the notes — are what this position is really asking you to learn.
- Once it feels automatic, move on to the next of the 2 shapes — together they cover the whole neck, and the same pattern repeats from there.
