Indian Classical: the Todi thaat
In Hindustani classical terms, C# Major maps to the Todi thaat (Western mode: Neapolitan Minor (Todi mode)). One of the most chromatic thaats — ♭2, ♭3, raised 4th (♯4), and ♭6. Equivalent to the Neapolitan Minor scale in Western theory (also called Hungarian Gypsy or Romanian minor). Intensely complex and expressive. Traditional listening time: Late morning (10 am–noon).
If you want to sing or practise in this key, set your tonic (Sa) to C#. Ragas built on this thaat:
- Miyan ki Todi — Full Neapolitan minor — ♭2 ♭3 ♯4 ♭6, the quintessential Todi. Intense pathos, high art.
- Gujari Todi — Neapolitan minor, slightly lighter ornamentation. Tender pathos, emotional.
- Multani — Todi scale with omitted notes in ascent — afternoon variant. Serious, weighty (Afternoon).
- Bilaskhani Todi — Todi ♭7 variant — adds flat 7th for extra darkness. Grief, depth (linked to Tansen legend) (Late night).
