The thavil artiste begins the allarippu 'thom thom tha thom thom tha, kuntha kunthakum, kuntha kunthakum. Then the nagaswaram artiste renders the ragam Gambeera Nattai elaborately and plays sorkattus beginning in madyama kaalam, gradually increasing the tempo into duritha kaalam and subsequently reduce the tempo to vilambam.
Once again, the artiste switches over to madyama kaalam, duritham and does thisram before increasing the pace to duritham and finally comes back to madyama kalam.
