Playing the G Dorian Scale on Guitar
The G Dorian scale on guitar consists of 7 notes: G, A, A#, C, D, E, F. The step pattern is W–H–W–W–W–H–W, where W is a whole step (2 semitones) and H is a half step (1 semitone). On the guitar fretboard, the G Dorian 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.

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 Dorian scale.
