Ten matras in vibhags of 2+3+2+3 — clap on 1, 3, and 8, wave on 6. The theka "Dhi Na | Dhi Dhi Na | Ti Na | Dhi Dhi Na" is one of the first asymmetric cycles every student masters. It is a pillar of madhya-laya khayal and a favorite for solo work: long enough for real phrases, odd enough to keep them honest.
The 2+3 limp is its personality — compositions exploit the unequal halves, and tihai arithmetic in tens builds real skill. Sooltaal shares the count but not the shape; the clap map is the difference.
