Scale Maps — Sitar
A 12-TET reference shelf beside the thaats engine — these maps name frets, not phrases, and they say so plainly.
The Sitar scale reference: choose a root and one of 24 Western types, and the notes arrive mapped across CGCGC with every root marked.
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.
