B Aeolian — Octave Mandolin

B Aeolian carries 7 notes per octave (modes 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 standard natural minor scale — melancholic, introspective, and deeply emotive. The most common minor sound in Western music.

Heard in: Pop, rock, classical, metal — the default minor sound of Western music.

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.
