E Whole Half Diminished — Irish Bouzouki

E Whole Half Diminished carries 8 notes per octave (symmetric family), drawn here across the Irish Bouzouki's GDAD courses with every root marked — melody is this instrument's first language, and these maps are its phrasebook.

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.

GDAD bends the grid on the top course: patterns climb in fifths until the final fourth, where every shape shifts by two frets — the maps below draw that kink instead of pretending it away.

Pick each note cleanly with alternating strokes before you ever tremolo it, and let the audio set the pitch in your ear as you go.
