The tabla is a widely popular North Indian percussion instrument used in the classical, popular and religious music of the northern Indian subcontinent. The instrument consists of a pair of hand drums of contrasting sizes and timbres. The term tabla is derived from an Arabic word which means "drum".
Most performers and scholars recognize two styles of gharana: Dilli Baj and Purbi Baj. Dilli (or Delhi) baj comes from the style that developed in Delhi, and Purbi (meaning eastern) baj developed in the area east of Delhi. They then recognize six gharānās of tabla. They appeared or evolved in the following order, presumably:
Each gharānā is traditionally set apart from the others by unique aspects of the compositional and playing styles of its exponents. For instance, some gharānās have different tabla positioning and bhol techniques. In the days of court patronage the preservation of these distinctions was important in order to maintain the prestige of the sponsoring court. Gharānā secrets were closely guarded and often only passed along family lines. Being born into or marrying into a lineage holding family was often the only way to gain access to this knowledge.
Today many of these gharānā distinctions have been blurred as information has been more freely shared and newer generations of players have learned and combined aspects from multiple gharānās to form their own styles. There is much debate as to whether the concept of gharānā even still applies to modern players. Some think the era of gharānā has effectively come to an end as the unique aspects of each gharānā have been mostly lost through the mixing of styles and the socio-economic difficulties of maintaining lineage purity through rigorous training.
Nonetheless the greatness of each gharānā can still be observed through study of its traditional material and, when accessible, recordings of its great players. The current generation of traditionally trained masters still hold vast amounts of traditional compositional knowledge and expertise.
This body of compositional knowledge and the intricate theoretical basis which informs it is still actively being transmitted from teacher to student all over the world. In addition to the instrument itself, the term "tabla" is often used in reference to this knowledge and the process of its transmission.
The larger drum, played with the other hand, is called bāyāñ (lit. "left"; aka. dagga, duggī, dhāmā). It is a bowl shape made of metal (or sometimes clay or wood, although not favored for durability). It has a much deeper bass tone, much like its distant cousin, the kettle drum.
The playing technique for both drums involves extensive use of the fingers and palms in various configurations to create a wide variety of different sounds, called bhols, which different gharanas posses and guard fiercely. On the bāyāñ the heel of the hand is also used to apply pressure, or in a sliding motion, so that the pitch is changed during the sound's decay. This "modulating" effect on the bass drum and the wide range of sounds possible on the instrument as a whole are the main characteristics that make tabla unique among percussion instruments.
Both drum shells are covered with a head (or puri) constructed from goat or cow skin. An outer ring of skin is overlaid on the main skin and serves to suppress some of the natural overtones. These two skins are bound together with a complex woven braid that also gives the entire assembly enough strength to be tensioned onto the shell. The completed head construction is affixed to the drum shell with a single continuous piece of cow or camel hide strap laced between the braid of the head assembly and another ring (made from the same strap material) placed on the bottom of the drum. The strap is tensioned to achieve the desired pitch of the drum. Additionally, cylindrical wood blocks are inserted between the strap and the shell allowing the tension to be adjusted by their vertical positioning. Fine tuning is achieved by striking vertically on the braided portion of the head using a small hammer.
The skins of both drums also have an inner circle on the head referred to as the siyāhī (lit. "ink"; a.k.a. shāī or gāb). This is constructed using multiple layers of a paste made from cooked rice mixed with a black powder of various origins. The precise construction and shaping of this area (especially on the smaller drum) is responsible for modification of the drum's natural overtones, resulting in the clarity of pitch and variety of tonal possibilities unique to this instrument. The skill required for the proper construction of this area is highly refined and is the main differentiating factor in the quality of a particular instrument.
For stability while playing, each drum is positioned on a toroidal bundle called chutta, consisting of plant fiber or another malleable material wrapped in cloth.
