Raga and Tala Theory
This domain tests structure: how ragas are grouped into families and how tala cycles are built and counted. Expect questions on thaats, jati, samay, the matra-vibhag scheme of named talas, and laya/layakari.
Raga structure
- Ten thaats of Bhatkhande: Bilawal, Khamaj, Kafi, Asavari, Bhairavi, Bhairav, Kalyan, Marwa, Poorvi, Todi. Each is a seven-note scale in ascending order; a raga is a melodic entity with aroha, avaroha, vadi, pakad and a time.
- Nine jati combinations arise because aroha and avaroha may differ in note count (e.g. audav-sampurna in Bhimpalasi).
- Samay chakra: eight prahars of roughly three hours. Bhairav is assigned the first prahar of the morning, Yaman the first of the night, Bhimpalasi the third of the afternoon, Malkauns the third of the night.
Tala structure
- Teental 16 (4+4+4+4); Jhaptal 10 (2+3+2+3); Rupak 7 (3+2+2); Ektaal 12 (2+2+2+2+2+2); Chautal 12 (4+4+4); Dhamar 14 (5+2+3+4); Jhoomra and Deepchandi 14 (3+4+3+4); Sultaal 10 (2+2+2+2+2); Dadra 6 (3+3); Keherwa 8 (4+4).
- Laya: vilambit, madhya, drut. Layakari: dugun (×2), tigun (×3), chaugun (×4), aad (3/2).
Worked example
"Where does khali fall in Jhaptal?" Jhaptal has 10 matras in vibhags 2+3+2+3, with tali on 1, 3 and 8 and khali on 6. Theka: Dhi Na | Dhi Dhi Na | Ti Na | Dhi Dhi Na. Khali falls on the first matra of the third vibhag, i.e. matra 6 - not matra 5. Count the vibhags, not the syllables.
Marks-losing traps
Assuming all 16-matra talas are Teental (Tilwada has the same count but a different theka and stress pattern); forgetting that Rupak is the only common tala with khali on sam; writing Dhamar as 3+4+3+4, which is Jhoomra/Deepchandi.
