Swar and Laya: Pitch and Tempo Foundations
Swar and Laya are the pitch and time foundations of tabla. The exam tests tuning concepts, the Hindustani note framework and tempo and layakari calculations.
Swar
- Swar means musical pitch. The saptak has 12 positions: Sa, re, Re, ga, Ga, ma, Ma, Pa, dha, Dha, ni, Ni.
- The dayan is tuned to the tonic (Sa) of the lehra or singer; the bayan is tuned to the lower Sa or Pa. The two drums must sound a stable interval, not an arbitrary high pitch.
- Fine tuning uses the gatta and syahi; the bayan pitch is lowered by adding syahi paste and raised by removing it.
Laya
- Laya is tempo, measured in matras per minute. Vilambit is slow, madhya medium and drut fast.
- Layakari is the ratio of played bols to the underlying matra: barabar (1:1), dugun (2:1), tigun (3:1), chaugun (4:1), aad (3:2) and kuwaad (5:4).
- Keep the taal cycle fixed; layakari changes subdivision, not the matra count.
Worked example
Teental has 16 matras. At 60 matras per minute, one matra lasts one second, so one avartan lasts 16 seconds. In dugun you play two bols per matra: 32 bols per avartan, one every 0.5 second. In aad (3:2), three bols occupy two matras, so the phrase must be spaced across the cycle, not squeezed into one matra.
Traps
Do not call layakari a new taal. Do not tune both drums to exactly the same pitch. Do not confuse matra (beat) with vibhag (bar). A fast tempo is not automatically drut laya if the matra count changes.
