A “dhol” or “dholak” is an Indian drum. This drum is played with your hands or using two drumsticks. The dhol is central to the baraat, or groom’s processional, and therefore is usually worn by the dhol player around the neck during that ceremony.
Here’s a fun video that shows some dhol players living their best lives at an Indian wedding:
The dhol playing starts around 1:25. Fair warning: Dhol music, like a lot of Indian bhangra music, has a strong beat. You’re going to want to dance.
