C# Locrian — Sitar

C# Locrian is 7 notes to the octave (modes family), drawn here across the Sitar's CGCGC strings with every C# marked, so home stays visible from anywhere in the pattern.

The most dissonant, unstable mode — the tonic chord is diminished (b5), making a true Locrian tonal center rare. Used for color and passing harmony.

Heard in: Metal riffs, jazz (half-diminished ø7 chords in ii°7 – V – i), horror and tension film scores.

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.
