Tala: Theoretical Framework, Matra, Vibhag, Laya, and Prescribed Talas
Tala questions test the arithmetic of cycles as much as the names. You must count matras, divide them into vibhags, place tali and khali, and relate laya to the theka.
Core framework
- Matra is a beat; vibhag is a division or bar; tali is a clap; khali is a wave; sam is the first matra of the cycle; avartan is one full cycle.
- Laya is tempo: vilambit, madhya and drut. Laya ratios include barabar, dugun, tigun and chaugun.
- Teentaal: 16 matras, vibhags 4+4+4+4. Jhaptal: 10, 2+3+2+3. Ektaal: 12, 2+2+2+2+2+2. Jhoomra: 14, 3+4+3+4. Dhamar: 14, 5+2+3+4. Rupak: 7, 3+2+2, with khali on sam. Keherwa: 8, 4+4. Dadra: 6, 3+3.
Worked example
In Teentaal, calculate dugun. The cycle has 16 matras. At dugun, two bols are placed in each matra, so one avartan contains 32 bols; sam still falls on matra 1. If the whole cycle is counted at double speed, the same 16 matras pass in half the time. State the bol count and keep sam fixed; do not invent a new 32-matra tala.
Traps
Khali is not the same as sam except in Rupak. Do not confuse vibhag count with matra count. Do not write Teentaal as 8+8. Tali numbers are not matra numbers. Dugun and tigun are laya ratios, not separate talas. Always show where sam and khali fall.
