F Whole Half Diminished, Mandolin Side

8 notes to the octave, mapped below onto this reader's GDAE fretboard, with every F 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.

Between chopping one number and chopping the next there is a beat and a half of nothing written down, and what goes in it is a fill drawn from here rather than from the page.

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