A# Whole Half Diminished — Tenor Banjo

A# Whole Half Diminished is 8 notes to the octave (symmetric family), drawn here across the Tenor Banjo's CGDA strings with every A# 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.

Fifths put seven semitones between neighbouring open strings, so a scale spreads three or four notes to a string and one fingering repeats across every pair — learned once, moved sideways.

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.
