G Whole Half Diminished on Violin

G Whole Half Diminished runs 8 notes to the octave. Below it is mapped onto this instrument's G–D–A–E fingerboard with every G marked, because what a player needs mid-number is not the pattern but where the root is when the harmony moves under it.

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 melody section plays written lines together, so a scale is section practice before it is anyone's vocabulary: several players putting the same pitch in the same place, with nothing on the neck to arbitrate.

Take it slowly against the playback until the geometry stops being geometry, then put it under a number in G minor and let the written line pick its own notes out of it.
