Tala and Rhythmic Theory: Vibhag, Laya and Tihai Arithmetic
Tala questions test whether you can describe a cycle precisely and then do simple arithmetic with it. Marks are lost by vague answers such as "Teentaal has sixteen beats" without vibhag, tali and khali. Always give the full structure.
Building blocks
- Matra: one beat. Vibhag: a group of matras. Tali: a clapped vibhag. Khali: a waved, empty vibhag. Sam: matra 1, the point of resolution. Avartan: one full cycle. Theka: the fixed bol pattern. Prakar: a variation. Tihai: a phrase repeated three times to end on sam.
- Jati of a tala: tishra (3), chatushra (4), khanda (5), mishra (7), sankirna (9).
Standard talas you must know cold
- Teentaal: 16 matras, 4+4+4+4, tali on 1, 5, 13, khali on 9.
- Ektaal: 12 matras, six vibhags of 2, tali on 1, 5, 9, 11, khali on 3 and 7.
- Jhaptaal: 10 matras, 2+3+2+3, tali on 1, 3, 8, khali on 6.
- Rupak: 7 matras, 3+2+2, khali on sam (1), tali on 4 and 6.
- Dadra: 6 matras, 3+3, khali on 4. Keharwa: 8 matras, 4+4, khali on 5.
- Laya is measured in matras per minute: vilambit slow, madhya medium, drut fast. Layakari includes barabar (1:1), dugun (2:1), tigun (3:1), chaugun (4:1), aad (3:2), kuadi (5:4).
Worked example: placing a tihai in Teentaal
Take a five-matra phrase. Three repetitions use 15 matras. For the last bol to fall on sam, the first repetition must begin on matra 3, so the phrases fall on 3–7, 8–12, and 13–16 plus sam. Rest before entry is 16 − 15 + 1 = 2 matras. Always check by counting backwards from sam.
Traps that cost marks
- Marking khali as a tali, or forgetting that Rupak's khali falls on sam.
- Writing a tihai with unequal repetitions.
- Calling any eight-matra cycle Keharwa without checking its vibhag.
