Tala Knowledge and Rhythmic Theory
This domain tests your grip on the cyclical framework of Hindustani rhythm: how many matras a tala carries, where its vibhags, tali and khali fall, and how laya and layakari are calculated.
Core vocabulary
Matra is one beat; vibhag is a division of the cycle; tali is a clap marking a vibhag; khali is a wave marking an empty vibhag; sam is the first matra and the point of resolution; avartan is one complete cycle; theka is the tabla's syllable pattern.
Talas you must know
- Teental: 16 matras, 4+4+4+4; tali on 1, 5, 13; khali on 9.
- Jhaptal: 10 matras, 2+3+2+3; tali on 1, 3, 8; khali on 6.
- Ektaal: 12 matras, six vibhags of 2; tali on 1, 5, 9, 11; khali on 3 and 7.
- Rupak: 7 matras, 3+2+2; its sam is itself khali; tali on 4 and 6.
- Dadra: 6 matras, 3+3; tali on 1; khali on 4.
- Keherwa: 8 matras, 4+4; tali on 1; khali on 5.
Laya and layakari
Vilambit, madhya and drut are the three speeds. Layakari multiplies the pulse: barabar (equal), dugun (double), tigun (triple), chaugun (quadruple).
Worked example
A bandish is set in Teental. Sam falls on matra 1. Khali falls on matra 9, the first matra of the third vibhag, so no clap sounds there. In dugun the performer places two syllables per matra but still completes the avartan across the same 16 matras, not in eight. Reasoning: count vibhags, not matras alone, and treat khali as a position rather than a softer volume.
Traps
Treating Rupak's sam as a tali; putting Jhaptal's khali on 7 instead of 6; writing Teental's khali on 5; confusing tigun with chaugun; halving the cycle when doubling the speed.
