Sound Tin and Ge together: index finger ringing gently on the dayan's maidan while the bayan speaks open underneath. Compared with Dha, the treble half is rounder and quieter, so Dhin reads as warm rather than bright.
Dhin populates the full (bhari) sections of thekas — Teentaal's "Dha Dhin Dhin Dha" — and drops its bass to become Tin through khali. Balance is the craft: the bayan should cushion the treble tone, not bury it.
