Construction

The dhol is a double-sided barrel drum played mostly as an accompanying instrument in regional music forms. In qawwali music, the term dhol is used to describe a similar, but smaller drum used with the smaller tabla, as a replacement for the left hand tabla drum. The typical sizes of the drum vary slightly from region to region. In Punjab, the dhol remains large and bulky to produce the preferred loud bass. In other regions, dhols can be found in varying shapes and sizes and made with different woods and materials (fiberglass, steel, plastic). The drum consists of a wooden barrel with animal hide or synthetic skin stretched over its open ends, covering them completely. These skins can be stretched or loosened with a tightening mechanism made up of either interwoven ropes, or nuts and bolts. Tightening or loosening the skins subtly alters the pitch of the drum sound. The stretched skin on one of the ends is thicker and produces a deep, low frequency (higher bass) sound and the other thinner one produces a higher frequency sound. Dhols with synthetic, or plastic, treble skins are common.

Playing

The dhol is played using one or two wooden sticks, usually made out of bamboo and cane wood. The stick used to play the bass side of the instrument, known as the dagga in Punjabi, is thick (roughly about 10 mm in diameter) and is bent in a quarter-circular arc on the end that strikes the instrument. The other stick, known as tihli, is much thinner and flexible and used to play the higher note end of the instrument.

The dhol is slung over the neck of the player with a strap usually made up of woven cotton. The surface of the wooden barrel is in some cases decorated with engraved patterns and sometimes paint.

In the pre-Partition era, dozens of rhythms were played on the Punjabi dhol, which corresponded to specific functions. However, with the decline or disappearance of some cultural practices, recent generations of dhol-players have become unfamiliar with many of these. At the same time, the growth of folkloric staged bhangra dance in Punjab inspired the creation of many new rhythms particular to that dance.

Some of the most common Punjabi dhol rhythms are bhangra (originating with the old, community bhangra dance), dhamaal (associated with many cultural functions, including worship at Sufi shrines), and kaharva, a dance and song rhythm. The staged "bhangra" dance, originating in the 1950s, gave special prominence to kaharva, for the performance of actions called luddi. In the 1970s, many more actions were added to staged bhangra to go with the kaharva rhythm, which started to become one of the most prominent rhythms associated with the dance. At the same time, this type of rhythm would be played on the dholki drum to accompany Punjabi songs. So when, in the 1990s, Punjabi pop songs began to evoke bhangra dance, they used the kaharva rhythm. It is known now by various names. Some dhol-players call it kaharva, its technical name, while other players in Punjab call it luddi to refer to the dance of that name. With the style of dhol-playing that developed in the U.K., the name chaal was adopted—probably in reference to the "chaal" movements it accompanies in modern bhangra—however, that term is not used elsewhere.
