Theory & Context

Why This Shape Works

A# Locrian in Open G tuning puts the notes A#, B, C#, D#, E, F#, G# under your fingers in a layout that feels unstable, angular and deliberately tense. Open G stacks a ready-made major chord under your fingers, which changes how the neck breathes and makes partial chords and droning double-stops easier to hear. On this page you can switch between all visible notes or five smaller positions, study a pre-rendered tab pattern for each zone and match the sound against chords that stay inside the scale. Because the interval formula is 1 b2 b3 4 b5 b6 b7, every diagram here is generated from exact semitone math instead of guessed text. Start with Position 1 to lock in the tonic, then connect Positions 2 and 3 so you can move into riffs, lead fills and improvised phrases without losing the key center.

Overview

Locrian sounds unstable, angular and deliberately tense and is especially useful for outside-sounding riffs, dark soundtrack parts and diminished movement. Open G feels rootsy, slide-friendly and chord-rich.

Pro Tip

Use the b5 carefully and resolve often or the line will sound completely ungrounded. In Open G, it is great for rhythm guitar ideas that need instant harmony.
