The dhol is a large barrel-shaped drum with a skin at each end, hung from the shoulder and played with two sticks: a heavy curved one, the dagga, on the bass side, and a thin cane, the tihli, on the treble side. Its sound carries across fields, and it was used once to announce news, gather people for war and drive the dancers at harvest.
The basic rhythm of bhangra, the chaal, comes from the dhol, and there are dozens of other rhythms for different dances and occasions: for the bride's arrival, for the Vaisakhi fair, for wrestling matches and for victory processions.
In Britain in the 1980s and 90s the dhol became the emblem of a new British Punjabi identity, and dhol players such as Gurcharan Mall in Birmingham trained thousands of young people. Today no Punjabi wedding anywhere in the world begins without one.
