About the A Locrian scale
A Locrian is used for jazz soloing over half-diminished chords and tense, dissonant passages. Think of it as the most unstable mode of all, restless and unresolved. It is A Phrygian with the fifth lowered.
Its notes are A, B♭, C, D, E♭, F, and G. The formula is H W W H W W W. It is the seventh mode of B♭ Major.
An unfretted guitar already sounds A, D, and G from this mode. On guitar, the deepest A rings from the open A string. The first three frets carry a complete octave of A Locrian, a genuine open-position shape.
Positions
Playable shapes for this scale up the neck. Tap any note to hear it.
CAGED
Five shapes, each anchored to a chord form you already know, the pop and rock default that ties your scales to your chords. The outlined notes are that chord, so you can see the C, A, G, E, and D shapes inside the scale.
3NPS
3NPS stands for 3 notes per string. It lays the scale out in seven even shapes for rock and metal lead, and favors speed because the picking pattern stays consistent across every string.
7-position system
7 four-fret boxes, one per scale degree, each a single hand position with almost no shifting. The jazz and classical way, from William Leavitt's Berklee method.
