A tabla is a pair of hand drums from the Indian subcontinent, that is somewhat similar in shape to the bongos. Since the 18th century, it has been the principal percussion instrument in Hindustani classical music, where it may be played solo, as an accompaniment with other instruments and vocals, and as a part of larger ensembles. It is frequently played in popular and folk music performances in India, Bangladesh, Afghanistan, Pakistan, Nepal and Sri Lanka. The tabla is an essential instrument in the bhakti devotional traditions of Hinduism and Sikhism, such as during bhajan and kirtan singing. It is one of the main qawali instruments used by Sufi musicians. The instrument is also featured in dance performances such as Kathak. Tabla is a rhythmic instrument.
The name tabla likely comes from tabl, the Arabic word for drum. The ultimate origin of the musical instrument is contested by scholars, though some trace its evolution from indigenous musical instruments of the Indian subcontinent.
The tabla consists of two small drums of slightly different sizes and shapes. Each drum is made of hollowed-out wood, clay or metal. The smaller drum (dayan/tabla) is used for creating treble and tonal sounds, while the primary function of the larger drum (baya/dagga) is for producing bass. They are laced with hoops, thongs and wooden dowels on its sides. The dowels and hoops are used to tighten the tension of the membranes for tuning the drums.
The playing technique is complex and involves extensive use of the fingers and palms in various configurations to create a wide variety of different sounds and rhythms, reflected in mnemonic syllables (bol)
The Indian theory traces the origin of tabla to indigenous ancient civilization. The stone sculpture carvings in Bhaja Caves depict a woman playing a pair of drums, which some have claimed as evidence for the ancient origin of the tabla in India. A different version of this theory states that the tabla acquired a new Arabic name during the Islamic rule, having evolved from ancient Indian puskara drums. The evidence of the hand-held puskara is founded in many temple carvings, such as at the 6th and 7th century Muktesvara and Bhuvaneswara temples in India. These arts show drummers who are sitting, with two or three separate small drums, with their palm and fingers in a position as if they are playing those drums. However, it is not apparent in any of these ancient carvings that those drums were made of the same material and skin, or played the same music, as the modern tabla.
The textual evidence for similar material and methods of construction as tabla comes from Sanskrit texts. The earliest discussion of tabla-like musical instrument building methods are found in the Hindu text Natyashastra. This text also includes descriptions of paste-patches (syahi) such as those found on a tabla. The Natyashastra also discusses how to play these drums. The South Indian text Silappatikaram, likely composed in the early centuries of 1st millennium CE, describes thirty types of drums along with many stringed and other instruments. These are, however, called pushkara; the name tabla appears in later periods.
This theory is based on the etymological links of the word tabla to Arabic word tabl which means "drum". Beyond the root of the word, this proposal points to the documentary evidence that the Muslim armies had hundreds of soldiers on camels and horses carrying paired drums as they invaded the Indian subcontinent. They would beat these drums to scare the residents, the non-Muslim armies, their elephants and chariots, that they intended to attack. However, the war drums did not look or sound anything like tabla, they were large paired drums and were called naqqara (noise, chaos makers).
Another version states that Amir Khusraw, a musician patronized by Sultan Alauddin Khalji invented the tabla when he cut an Awaj drum, which used to be hourglass shaped, into two parts. However, no painting or sculpture or document dated to his period supports it with this evidence nor it was found in the list of musical instruments that were written down by Muslim historians. For example, Abul Fazi included a long list of musical instruments in his Ain-i-akbari written in the time of the 16th century Mughal Emperor Akbar, the generous patron of music. Abul Fazi's list makes no mention of tabla.
The third version credits the invention of tabla to the 18th century musician, with a similar sounding name Amir Khusru, where he is suggested to have cut a Pakhawaj into two to create tabla. Miniature paintings of this era show instruments that sort of look like tabla. This theory implies that tabla emerged from within the Muslim community of Indian subcontinent and were not an Arabian import. However, scholars such as Neil Sorrell and Ram Narayan state that this legend of cutting a pakhawaj drum into two to make tabla drums "cannot be given any credence".
The tabla consists of two single-headed, barrel-shaped small drums of slightly different sizes and shapes: baya and daya for left and right drums, respectively
The smaller drum, played with the dominant hand, is called dayan (literally "right" side), dāhina, siddha or chattū, but is correctly called the "tabla." It is made from a conical piece of mostly teak and rosewood hollowed out to approximately half of its total depth. The daya tabla is played by the musician's right hand (dominant hand), and is about 15 centimetres (~6 in) in diameter and 25 centimetres (~10 in) high. The drum is tuned to a specific note, usually either the tonic, dominant or subdominant of the soloist's key and thus complements the melody. This is the ground note of the raga called Sa (tonic in India music). The tuning range is limited although different dāyāñs are produced in different sizes, each with a different range. Cylindrical wood blocks, known as gatta, are inserted between the strap and the shell allowing tension to be adjusted by their vertical positioning. Fine tuning is achieved while striking vertically on the braided portion of the head using a small, heavy hammer. While tabla usually features two drums, a tabla tarang may consist of 10-16 dayas to perform melodies based on several ragas.
The baya tabla is a bit bigger and deep kettledrum shaped, about 20 centimetres (~8 in) in diameter and 25 centimetres (~10 in) in height. It played with the non-dominant hand, is called bāyāñ (literally "left") duggī or dhāmā (correctly called "dagga"), has a much deeper bass tone, much like its distant cousin, the kettle drum. The bāyāñs can be found to be made up of many different types of materials. Brass is the most common, copper is more expensive, but generally held to be the best, while aluminum and steel are often found in inexpensive models. Sometimes wood is used, especially in old bāyāñs from the Punjab. Clay is also used, although not favored for durability; these are generally found in the North-East region of Bengal. The baya construction and tuning is about a fifth to an octave below that of the daya drum. The musician uses his hand's heel pressure to change the pitch and tone colour of each drum during a performance.
The head of each drum has a central area of "tuning paste" called the syahi (lit. "ink"; a.k.a. shāī or gāb). Syahi is common in many drums of Indian origin. This method allows these drums to produce harmonic overtones and is responsible for their unique sound. Syahi is constructed using multiple layers of a paste made from starch (rice or wheat) mixed with a black powder of various origins. The precise construction and shaping of this area is responsible for modification of the drum's natural overtones, resulting in the clarity of pitch (see inharmonicity) and variety of tonal possibilities unique to this instrument which has a bell-like sound. 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. The earliest discussion of these paste-patches are found in the Hindu text Natyashastra. For stability while playing, each drum is positioned on a toroidal bundle called chutta or guddi, consisting of plant fiber or another malleable material wrapped in cloth. They are commonly played while sitting cross-legged on the floor.
