G Half Whole Diminished Scale — Guitalele

The G Half Whole Diminished scale has 8 notes per octave and belongs to the symmetric family. Here it is mapped onto the Guitalele's ADGCEA strings, position by position, with the root highlighted so the pattern anchors to G wherever you play it.

Tense, symmetrical, and slightly sinister — alternating half and whole steps pack in the b9, #9, #11, and 13, so it sounds like a dominant chord stretched to breaking point. Edgy, jazzy, and restless.

Heard in: Jazz lines over 13b9 dominant chords, fusion, film-noir and horror scoring — the sound of a V chord that refuses to settle.

Guitar shapes work unchanged on guitalele — finger them exactly as charted; every shape sounds a perfect fourth higher than on guitar.

Play each position slowly against the audio until the shape and the sound lock together, then take it to the progressions in G to use it over real changes.
