Indian Classical: the Marwa thaat
In Hindustani classical terms, B Major maps to the Marwa thaat (Western mode: Lydian ♭2 (Marwa mode)). Unique to Indian music — the 'Marwa mode.' A ♭2 and raised 4th (♯4) with no perfect 5th in the characteristic phrases. Creates intense tension and yearning. Has no exact Western parallel; closest to a Lydian scale with flat second (Neapolitan Lydian). Traditional listening time: Sunset (5–7 pm).
If you want to sing or practise in this key, set your tonic (Sa) to B. Ragas built on this thaat:
- Marwa — Lydian ♭2 — ♭2 and ♯4, avoids Pa (5th) — extreme tension. Intense yearning, sunset dread.
- Puriya — Lydian ♭2 with strong ♭2 emphasis — similar to Marwa but sweeter. Romantic longing, twilight.
- Sohini — Lydian ♭2 pentatonic (omits 2nd and 6th). Restless, passionate (Night).
- Lalit — Marwa scale with both ♮4 and ♯4 (double madhyam). Deep meditation, dawn (Pre-dawn).
