Three Days Before a Practical: Repairing and Tuning a School Tabla Set
A school's tabla set must be ready for a board practical three days away, in a humid monsoon week. The dayan's syahi has a chip at the edge and the drum now buzzes metallically on 'na' and 'tin'; the tuning blocks are jammed and a wedge has been forced in beside one of them. The bayan's skin has gone slack, its 'ghe' is a dull thud, and a hairline crack runs from the rim toward the centre while the syahi is flaking. The student's father proposes three fixes: applying fevicol along the crack, sanding the chipped syahi smooth, and holding both drums over a room heater to dry the skins. The set has been kept in a closed cupboard with the bayan resting face-down on a folded blanket. The tanpura stands at C#.
1. Evaluate the three proposed repairs. Which will work, which will ruin the instrument, and why?
Read the worked answer
None of the three should be done as proposed.
- Fevicol on the bayan crack - reject. The crack is in a vibrating skin under tension; adhesive stiffens that zone, kills the mode that produces 'ghe', and will fail as the skin flexes. A hairline rim crack on a bayan is usually stabilised by a maker (patch or re-skinning), not by glue. At three days' notice the realistic options are: play the bayan as it is and keep the 'ghe' light, or borrow a bayan.
- Sanding the dayan syahi - reject. Syahi is a graded, layered deposit; sanding removes mass unevenly and changes the pitch and the 'tin/na' response permanently. A chipped edge causes the metallic buzz because the chip breaks the ring; the correct course is for a maker to add and level syahi, or to use a different dayan for the exam. A tiny dab of syahi mix by an experienced hand is the only field remedy.
- Heater drying - reject outright. Rapid drying of a damp, slack skin is the standard route to a split; heat also warps the shell and loosens the syahi. Dry gradually in a shaded, ventilated room.
Also wrong, though not proposed: storing the bayan face-down on a blanket traps moisture against the skin. Hang or stand it in air, shell down.
2. Set out the tuning procedure for the dayan and the bayan, given the dayan must reach C#.

Dayan (tuned drum, to Sa = C#):
- Seat the shell, clear the braid, and check the gatta are free - the jammed wedge must come out, because the ring cannot be tensioned evenly with one blocked point.
- Work around the ring in small increments, alternating opposite gatta, so the ring stays level; a wedge forced at one point is what produced the jamming in the first place.
- Tap the syahi-bearing area and compare with the tanpura's C#; approach pitch from below rather than overshooting and slackening.
- Use a little chalk or rosin under slipping gatta so the tuning holds through the exam.
- Because the syahi is chipped, expect the 'na'/'tin' to be uneven at best; tune for the cleanest 'dha' and warn nobody on stage.
Bayan (bass drum):
- Pegs first for coarse pitch - aim for the mandra Sa of the tanpura.
- Fine-tune by syahi mass, not by moisture: small additions to thicken the bass, careful removal to raise it.
- If the skin is genuinely slack from humidity, the honest fix is a maker's re-tensioning; on the day, tune to the best available pitch and support 'ghe' with a slightly firmer stroke.
Test both with the tanpura sounding, playing 'dha' and 'ghe', not with an isolated meter.
3. What care and storage routine should the school adopt from now on, and what should the student be told on exam day?
Read the worked answer
Routine:
- Store in a dry, ventilated cupboard - not a sealed one, and not against an outside wall. In monsoon, a moisture absorber in the cupboard is sensible; direct heat is not.
- Never rest a drum face-down on cloth: the skin must breathe, and the bayan's syahi is easily bruised. Stand drums on the shell or hang them.
- Loosen nothing after each use except where the instrument will sit unused for weeks; constant retuning shortens skin life more than steady tension does.
- Keep a tuning wedge, chalk/rosin, a spare braid and a soft cloth in the case; inspect syahi edges and braids monthly.
- Teach students to tap tuning gatta with the heel of the hand or a light mallet, never to hammer a single wedge.
- Any crack, chip or flaking syahi goes to a maker in the vacation, not to a parent with glue.
On exam day:
- Arrive early and tune to the tanpura at C#, in the hall, not in the corridor.
- Have a backup dayan if the buzz persists; a borrowed drum tuned well is better than a familiar drum that buzzes on every 'tin'.
- Keep the bayan's 'ghe' stroke slightly firmer to compensate for the slack skin, and avoid exposing the chipped area of the syahi in fast 'na' work.
