Playing the G Lydian Scale on Guitar
The G Lydian scale on guitar consists of 7 notes: G, A, B, C#, D, E, F#. The step pattern is W–W–W–H–W–W–H, where W is a whole step (2 semitones) and H is a half step (1 semitone). On the guitar fretboard, the G Lydian scale is most commonly played using two-notes-per-string fingering across a single position, with the root G positioned on the 6th or 5th string.

How to Practice G Lydian on Guitar
Start with a metronome at 60 BPM playing eighth notes ascending and descending. Use alternate picking (down-up). Focus on clean hammer-ons and pull-offs between scale tones. Increase the tempo by 5 BPM once each pass is clean. Practice in one fretboard position first, then expand across the neck using CAGED positions to cover the full range of the G Lydian scale.
