G# Blues — Octave Mandolin

G# Blues carries 6 notes per octave (blues family), drawn here across the Octave Mandolin's GDAE courses with every root marked — melody is this instrument's first language, and these maps are its phrasebook.

The minor pentatonic with a b5 "blue note" wedged in — that one extra note adds grit, tension, and a sly, vocal quality. Tough, expressive, and unmistakably bluesy.

Heard in: Blues, rock, jazz, rhythm and blues, and boogie-woogie — Delta and Chicago blues, Hendrix, Clapton, Stevie Ray Vaughan.

Pure fifths make scales symmetrical: the finger pattern that plays octave mandolin notes on one course pair plays them on every other pair, so one shape learned is twelve keys owned.

Pick each note cleanly with alternating strokes before you ever tremolo it, and let the audio set the pitch in your ear as you go.
