Construction, Tuning, Maintenance and Care of the Tabla and Related Instruments
Overview
This domain tests practical knowledge of tabla anatomy, tuning and care. Questions may ask about parts, the function of syahi, tuning direction, or correct storage.
Anatomy and function
- Dayan: right-hand treble drum; tuned to the tonic or dominant.
- Bayan: left-hand bass drum; provides low, bendable pitch.
- Syahi: black central patch; controls resonance and pitch.
- Chat/maidan: main skin area.
- Gajra: braided rim.
- Gatta: wooden tuning blocks under the lacing.
- Tasma: lacing/straps.
- Chanti: rim edge.
Tuning and care
Tap the gatta gently with the hammer to raise or lower tension; small increments, then check against a tanpura or harmonium. Tune the dayan to Sa or Pa, and the bayan lower. Keep the instrument dry, avoid direct sun and moisture, cover it when not in use, and never strike or press the syahi with oily hands. Loosen tension if storing for a long period.
Worked example
The dayan sounds flat against the tanpura's Sa. Reasoning: increase tension by tapping the gatta downward in small, even steps around the rim, checking pitch after each pass. If you overshoot, tap upward slightly. Do not hammer the syahi; that damages the patch and ruins the tone.
Traps
Tuning is not "tighten until it sounds high"-the dayan must match a reference pitch. The bayan is not tuned to the same pitch as the dayan. Water and direct heat are damaging. Do not use force on the gatta or ignore the condition of the tasma.
