D# Whole Half Diminished — Plectrum Banjo

D# Whole Half Diminished is 8 notes to the octave (symmetric family), drawn here across the Plectrum Banjo's CGBD strings with every D# marked, so home stays visible from anywhere in the pattern.

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.

The long neck puts the same note in more places than four strings usually offer, so these maps show the whole CGBD field and leave the choice of route to you.

Run it against a click at a tempo where every note gets the same weight. On a banjo an uneven scale is audible immediately — the instrument gives you no sustain to hide behind.
