D Whole Half Diminished, Lap Steel Side

8 notes to the octave, mapped below onto this reader's CEGACE neck, with every D called out. Those markers are the useful part mid-bar: a chart moves under you, and the thing you need is where the root went — not where the pattern started.

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.

With a bar instead of fingers, a scale is a set of stopping places rather than a set of grips, and the slide between two of them is as much of the line as either end.

Play it slowly against the audio until the shape stops being a shape, then take it to a chart counted in D and let the numbers pick their own notes out of it.
