Structure, Tuning and Maintenance of the Tabla
This section covers the physical structure, tuning and care of the tabla. The exam tests part names, materials, the function of the syahi and gajra, and safe tuning adjustments.
Structure
- The daya is usually a wooden shell, often sheesham or khair, with a goatskin head. The bayan is metal, usually copper or brass, and sometimes clay.
- The head has syahi (black patch), maidan (clear skin), kinar (rim) and gajra (braided edge). The syahi adds weight and produces the characteristic pitched tone.
- The bayan has a wider skin and a larger syahi; pressure from the left wrist or heel changes its pitch and gives the bass glide.
- The two drums are joined by a cloth or leather strap and tuned with small wooden pegs or blocks called gattas.
Tuning and maintenance
- Tune the daya by adjusting tension at the gajra or gattas; small changes are better than large ones.
- Tune the bayan to a suitable bass note, often the tonic or a supportive pitch, using the gattas and, where present, the tuning strap.
- Keep the heads dry. Moisture dulls the syahi and changes pitch. Store the instrument away from direct heat and damp.
- Do not hammer the syahi itself; work on the rim or gajra. Replace worn lacing carefully and keep the shell free of cracks.
Worked example
A daya sounds flat and the gajra is loose. Reason: the head lacks tension, so the pitch is low. Tighten the gajra or gattas gradually, testing after each small adjustment. Do not strike the syahi with the hammer, because that can damage the patch and spoil the tone.
Traps that cost marks
Do not say the syahi is the tuning peg. Do not tune by hitting the black patch. Do not confuse the bayan’s metal shell with the daya’s wooden shell. Do not overtighten in one step; the head may split.
Exam focus
Label the parts on a diagram and explain one safe tuning adjustment for each drum.
