Playing the G Blues Scale on Guitar
The G Blues scale on guitar consists of 6 notes: G, A#, C, C#, D, F. The step pattern is A–W–H–H–A–W, where W is a whole step (2 semitones) and H is a half step (1 semitone). On the guitar fretboard, the G Blues 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 Blues 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 Blues scale.
