E Whole Half Diminished — Sitar

E Whole Half Diminished is 8 notes to the octave (symmetric family), drawn here across the Sitar's CGCGC strings with every E 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.

Five strings tuned CGCGC put a 12-TET scale map in an honest place: it names every fret and marks every root, but it cannot draw meend, the pitch a sitarist bends into rather than frets outright. Read this as a Western scale laid over the strings, and the thaats engine as the raga-native classification sitting beside it.

A sitarist does not run this scale as a ladder — a raga moves through its own ascent and descent, skips notes deliberately, and lingers on the swaras it favors. Treat this map as a place to find pitches, not a phrase to play.
