The tabla is a popular Indian percussion instrument used in the classical, popular and religious music of the Indian subcontinent and in Hindustani classical music. The instrument consists of a pair of hand drums of contrasting sizes and timbres.
Tabla is a pair of drums. It consists of of a small right hand drum called dayan and a larger metal one called bayan.
The tabla has an interesting construction. The dayan (right hand drum) is almost always made of wood. The diameter at the membrane may run from just under five inches to over six inches. The bayan (left hand drum) may be made of iron, aluminium, copper, steel, or clay; yet brass with a nickel or chrome plate is the most common material. Undoubtedly the most striking characteristic of the tabla is the large black spot on each of the playing surfaces. These black spots are a mixture of gum, soot, and iron filings. Their function is to create the bell-like timbre that is characteristic of the instrument.
Playing technique involves extensive use of the fingers and palms in various configurations to create a wide variety of different sounds, reflected in the mnemonic syllables (bol). The heel of the hand is used to apply pressure or in a sliding motion on the larger drum so that the pitch is changed during the sound’s decay.
