G Whole Half Diminished — Tenor Guitar

G Whole Half Diminished is 8 notes per octave (symmetric family), drawn here as position boxes on the Tenor Guitar's CGDA grid with the root flagged in each — learn one box deeply, then let the overlaps carry you into the next.

Unstable and eerie — alternating whole and half steps, with the b3, b5, and 6 spelling a diminished seventh chord in every direction. Ominous, symmetrical, and unresolved.

Heard in: Diminished seventh chords in classical and jazz, horror and suspense scores, Bartok and Stravinsky, and neoclassical metal.

Fifths spread each scale wider per string than a standard guitar — fewer notes per position, longer reaches, and patterns that repeat cleanly across every string pair.

Play each box top to bottom until the roots feel like home base, then practice crossing between boxes mid-phrase — neck freedom is exactly that crossing, nothing more.
