Indian Classical: the Khamaj thaat
In Hindustani classical terms, D Major maps to the Khamaj thaat (Western mode: Mixolydian). Mixolydian mode — major scale with a flat 7th. Common in blues, rock, and folk. Earthy, sensuous quality. Traditional listening time: Late evening to night.
If you want to sing or practise in this key, set your tonic (Sa) to D. Ragas built on this thaat:
- Khamaj — Mixolydian with both ♮7 and ♭7 (ascending/descending difference). Sensuous, romantic.
- Des — Mixolydian pentatonic (omits 2nd & 6th). Patriotic, folk-like (Late night).
- Jaijaiwanti — Mixolydian with both ♭3 and ♮3 — complex chromatic tension. Majestic, complex (Midnight).
- Tilak Kamod — Mixolydian with added ♭3 colour notes. Light, amorous (Night).
- Jhinjhoti — Mixolydian ♭3 (between Dorian and Mixolydian). Gentle, devotional (Night).
