Tihai Landing on Khali and Dugun Drift in Teental
A sitar candidate's 15-minute practical ends with a drut gat in teental. The tabla player fixes the tempo at 150 bpm, so one matra lasts 0.4 seconds. The candidate plans barabar, then dugun, then a tihai built from a three-matra phrase repeated three times without pause, then a final sam with the theka. In the last run-through the tihai began on matra 6 and finished on matra 14, and the examiner noted that it was falling on khali rather than sam. In dugun her sam arrived one matra after the tabla's, and the gap widened by the third cycle. She counts 'dha dhin dhin dha' as four separate beats and practises with a metronome that accents every beat equally. The gat's mukhda is four matras long and ends on sam. She has not rehearsed with this tabla player before, and twenty minutes remain.
1. Calculate where the three-matra-phrase tihai must begin so that it ends on sam, show the arithmetic and the matras covered, and give one alternative that starts on a tali.

Teental has 16 matras. Three repetitions of a three-matra phrase with no pause occupy 3 × 3 = 9 matras. To finish on sam, the last matra of the third phrase must be matra 16, so the first matra is 16 − 9 + 1 = 8.
Phrases therefore run 8–9–10, 11–12–13 and 14–15–16, resolving to sam at the next 1. Note that this start lies on matra 8, the last matra of vibhag 2 (5–8), and the first phrase immediately crosses khali at 9. That is legitimate, but it explains why her earlier attempt sounded ambiguous: an error of two matras moved the whole structure into the khali region and made the resolution land on 14.
Alternative that begins on a tali: use a four-matra phrase with no pause, 3 × 4 = 12 matras, starting at 16 − 12 + 1 = 5. That gives 5–8, 9–12 and 13–16, beginning on tali 5 and ending on sam. At 150 bpm each repetition lasts 1.6 seconds, which is comfortable.
2. Diagnose the dugun drift and prescribe a counting method that will hold at 150 bpm.

At 150 bpm, dugun means 300 bols per minute, five per second. Counting 'dha dhin dhin dha' as four separate beats gives 32 counts per cycle and no landmark at 9; the theka's own symmetry (two identical 'dha dhin dhin dha' halves) hides khali, so the ear has nothing to check against. She is therefore counting bols while the tabla player is counting matras, and the mismatch shows first at khali, then accumulates.
Remedy: count 16 matras, not 32 bols. Mark 1 with a clap, 5 with a clap, 9 with a silent wave (khali), 13 with a clap, and say the dugun pairs as 'dha-ge / na-ti' inside each matra. Practise with a tabla or metronome at 100 bpm for four cycles, then 120, then 150, always checking that her sam coincides with the tabla's 'dha'. Ask this tabla player to keep a plain theka rather than mirror her line; a theka that imitates the solo removes the grid she needs. Record once and listen only for whether each sam is together.
3. Decide the layakari sequence for the performance and justify the exclusions.

Recommended sequence: barabar for two avartans of the gat, dugun for four to six avartans, a short return to barabar, then the tihai at barabar, then one final sam with the theka.
Reasoning: barabar establishes the grid and lets the tabla player settle; dugun is the most audible and most examinable layakari at this tempo; returning to barabar before the tihai is a deliberate risk reduction, because the tihai's arithmetic is easiest to hear and control when one matra equals one unit. At 150 bpm, aad (3/2) would demand subdivision at 225 bpm and kuad (5/4) would stretch the cycle to 20 matras - both are calculable but leave no margin for a first-time tabla partner. A tihai attempted inside dugun doubles the number of failure points for the same marks. If the examiner specifically asks for a second layakari, offer aad in the vilambit-section equivalent or in a slower tempo rather than in the drut gat.
