G Whole Half Diminished — Oud

G Whole Half Diminished is 8 notes to the octave (symmetric family), drawn here across the Oud's CFADGC courses with every G marked, so home stays visible from anywhere on the fingerboard.

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.

Six courses tuned CFADGC give a scale plenty of room, but the honest caveat travels with every map here: maqam scales bend intervals a 12-position board cannot draw, so these positions are a reference grid, not the microtonal reality a taqsim actually plays. Every root is marked so the pattern never loses home even where the notation and the tradition part ways.

Play it as a reference, not a rulebook: the pattern gives you every 12-TET position the scale touches, but a maqam-trained ear will pull some of those tones a quarter step in performance. Learn the grid first, then learn where the tradition asks you to leave it.
