The 16-Bol Sthayi That Will Not Land on Sam
A student is preparing a khayal for a school competition. Her sthayi in raga Yaman has 16 bols, one per matra, in teental; the tabla player sets the tempo at 60 matras per minute, and the marking scheme awards five marks for 'sam-par layakari'. For the second avartan she plans to sing the same sthayi in aad layakari - three bols in the space of two matras - then return to barabar for the antar, which runs to 20 bols. In rehearsal the line finishes early, the tabla player keeps going, and the sam of the next avartan arrives while she is silent; the recording shows a gap of about five matras. Her teacher says the fault is arithmetic, not voice, and asks her to re-plan before the next class, keeping the same raga, the same 60 bpm and the same aad layakari.
1. Show the arithmetic that produces the five-matra gap, and explain why the fault lies with the bol count rather than with her singing.

Step 1 - the cycle in time. Teental is 16 matras. At 60 matras per minute, one matra = 1 second, so one avartan = 16 seconds.
Step 2 - what aad does to a bol. Aad layakari is 3:2 - three bols in the time of two matras. Each bol therefore occupies 2/3 of a matra.
Step 3 - length of the 16-bol line in aad. 16 bols × (2/3 matra per bol) = 32/3 = 10⅔ matras.
So the line ends two-thirds of the way through matra 11 - inside the third vibhag (matras 9–12), not at a vibhag boundary and certainly not at sam.
Step 4 - the wait. Sam of the next avartan is matra 17. Rest = 16 − 10⅔ = 5⅓ matras, which is the gap heard on the recording. The arithmetic predicts the observed symptom exactly.
Why it is not a voice fault. She is singing the correct bols at the correct layakari; the tempo is steady and the tabla player is blameless. The mismatch is dimensional: a bol count of 16 divided by a ratio of 3:2 cannot produce a whole number of matras. For sam to fall on the last bol's completion, the bol count must be divisible by 3.
Check the antar too. 20 bols × 2/3 = 13⅓ matras, leaving 2⅔ matras of silence. The same defect is present; it will simply be less audible because the antar is followed by relaxation rather than by the next sam.
2. Propose a revised plan that keeps the same raga, tempo and aad layakari but puts sam where the marking scheme wants it. Give the numbers for your chosen scheme.

Principle. Total bols in aad must be a multiple of 3, and the resulting matra count should be 16 (one full avartan) or a clean fraction that a tihai can complete.
Option A (recommended): a 24-bol aad statement = exactly 16 matras.
- 24 bols × 2/3 = 16 matras = one avartan, sam to sam, no fillers.
- Build the 24 bols as the 16-bol sthayi plus an 8-bol cadential phrase from the same composition, or as a 12-bol line sung twice. Either way, count the bols before rehearsal, not during it.
- The return to barabar then happens on the following sam with the antar, which she should re-cut to 16 bols so that it too sits one bol per matra.
Option B: run the aad only to a vibhag boundary.
- 12 bols × 2/3 = 8 matras: exactly two vibhags, ending on matra 9 (which is khali in teental). Then sing barabar for matras 9–16 with an 8-bol phrase. This is safe and easy to hear, but the return to barabar lands on khali, so the stress must be managed - a quiet landing, then rebuild to sam.
Option C: keep the 16-bol line and fill the tail.
- The tail is 5⅓ matras. A tihai of three phrases must therefore be 1⅔ matras each. 1⅔ matras in aad = 2.5 bols - not a whole bol. This is why C is unattractive and why teachers push students towards A: the fillers never divide cleanly.
What to say in the viva: the bol count, not the layakari, was the variable. Aad is a ratio, and a ratio only returns to its starting point when the quantity it is applied to is commensurate with it.
3. In your revised scheme, where does khali fall, and what must the singer and the tabla player each do about it? Explain why the tabla player should not change to aad.

Where khali falls. In teental, khali is matra 9 (the third vibhag opens with it); tali falls on 1 (sam), 5 and 13.
- In Option A (24 bols in aad) the cycle is 16 matras, so matra 9 begins after 8 matras = 12 bols. Khali therefore coincides with bol 13 - the start of the second half of the line.
- In Option B (12 bols in aad to matra 9) khali falls exactly where the singer returns to barabar, i.e. on the first bol of the barabar phrase.
The singer's job. Khali is an unaccented position. Do not put a taan peak, a high Sa, or a text stress on bol 13; let the phrase pass through it lightly and build towards sam at bol 25 (Option A). Practise the aad line against a clap-and-wave count so the body knows matra 9 before the voice reaches it.
The tabla player's job. Keep the theka in barabar and mark khali clearly - a lighter, closed stroke. The tabla is the grid; the khali is a signpost on it. If the tabla player also doubles up into aad, the reference disappears and both performers are guessing.
Why the tabla must not change. Layakari is a relationship between the singer's phrases and a fixed cycle. The moment the theka moves with the voice, there is nothing for the layakari to be 'against', and the examiner hears two people playing rather than one person improvising over a cycle. The tabla's steadiness is what makes 3:2 audible as 3:2.
