Indian Classical: the Kafi thaat
In Hindustani classical terms, A# Major maps to the Kafi thaat (Western mode: Dorian). Dorian mode — minor scale with a natural 6th. Common in jazz and folk music (Santana, 'So What' by Miles Davis). In Indian music it gives a gentle, romantic character. Traditional listening time: Afternoon to midnight.
If you want to sing or practise in this key, set your tonic (Sa) to A#. Ragas built on this thaat:
- Kafi — Pure Dorian — ♭3 and ♭7, natural 2nd and 6th. Romantic, folk-like, seasonal (Holi).
- Pilu — Dorian with chromatic passing notes — very flexible. Light classical, semi-classical (Any time).
- Bhimpalasi — Dorian pentatonic (omits 2nd & 6th). Meditative, longing (Afternoon).
- Bageshri — Dorian with omitted 5th in ascent — intimate, introspective. Romantic, feminine (Late night).
- Patdeep — Dorian with both ♮3 and ♭3 in descent. Tender, seasonal (Afternoon).
