F# Whole Half Diminished — 5-String Banjo

F# Whole Half Diminished is 8 notes to the octave (symmetric family), drawn here across the 5-String Banjo's gDGBD strings with every F# 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.

A scale here always has to negotiate with the short g: it is one fixed pitch that belongs to some keys and argues with others, so these maps mark where it falls inside the pattern instead of hiding it.

Learn it as melody first and picking pattern second: get the notes under the left hand, then work out which right-hand fingers reach them without breaking the pulse. That second question is the one that takes the time.
