B Mixolydian Mode in Practice

Enharmonically equivalent to Cb major, it is used in orchestral writing and some jazz compositions. On guitar, B positions offer open-string resonance for fingering positions for this scale.

The Mixolydian mode is like a major scale with a flat 7th, giving it a bluesy, rock quality. It appears in rock, blues, folk, and Celtic music and is essential for dominant chord improvisation.
