A Sitar with a Buzzing Pa Six Days Before the Practical
A candidate's sitar has six main strings and thirteen sympathetic strings. It is tuned with Sa = C#, although the accompanying tanpura is tuned to C. In August humidity of about 80%, the Pa string has developed a metallic buzz near the bridge, and meend on Dha chokes when the string is pulled toward Ni. The jawari has visibly flattened on the treble side, and there is a worn groove under the Pa string. The candidate has a spare set of strings, fine sandpaper, a small file and a tuning app, but no luthier nearby. The practical is in six days, and the candidate will play a 10-minute item in Yaman plus a Jhaptal composition. A friend suggests filing the bridge immediately, another suggests tuning everything down a whole tone, and a third says the buzz is 'just the taraf strings resonating'.
1. Give a diagnostic sequence to identify the cause of the buzz before any adjustment is made, and say what each test rules in or out.

The first rule is do not file the bridge until the source is isolated. A buzz on one string can come from at least five places: the string winding, the bridge groove, the jawari profile, a loose taraf, or a loose fitting (bead, peg, or bridge foot). A workable sequence:
- Mute all thirteen taraf strings with a soft cloth or paper strip and play Pa. If the buzz disappears, the cause is sympathetic resonance or a loose taraf, not the main string. This directly tests the friend's claim.
- Play the open Pa string softly and loudly. If the buzz appears only at high volume, the string is likely hitting the bridge unevenly; if it appears at all volumes, suspect a worn groove or a kink in the winding.
- Press the string at the first fret/position and play. If the buzz persists, the problem is between the bridge and the nut, not the left-hand technique.
- Inspect the groove with a torch and run a fingernail along the string. A dented winding or a blackened groove points to string or bridge wear.
- Test the neighbouring strings. If Ma and Dha are clean, the problem is local to Pa; if all treble strings buzz, the jawari is flattened.
Only after these tests should the candidate decide. Filing the bridge is irreversible and should be the last option, especially with a worn groove already present.
2. The diagnosis points to a worn groove plus a flattened treble-side jawari. What should the candidate do in six days, and how should the tuning conflict with the tanpura be resolved?

With six days left, the priority is stability, not perfection. A luthier's jawari reshaping is a skilled job; a candidate filing the bridge at home risks making the sitar unplayable. A sensible plan is:
- Change the Pa string first. A new string removes the worn winding and sits differently in the groove. Tune it gently and let it settle for 24–48 hours, retuning several times a day; new strings drift, especially in 80% humidity.
- Clean and lightly burnish the groove with fine sandpaper wrapped around a finger, working along the string direction, not across it. The aim is to remove burrs, not to reshape the curve. A few light passes, then re-test.
- Control humidity by keeping the instrument in a case with a silica gel pack when not in use; sudden dryness can crack the bridge or the table.
- Do not file the treble side unless the candidate has practised jawari work. A flattened jawari can sometimes be compensated by a slight bridge tilt or a thin shim, but these are also skilled adjustments.
- Resolve the tuning mismatch: the sitar at C# against a tanpura at C will beat audibly and make the examination sound out of tune even if the playing is correct. The candidate should tune the sitar to C for the exam and re-tune the taraf accordingly, or ask the accompanist to tune to C#. The safer choice is to match the tanpura, because the examiner hears the combined sound. Tuning down also reduces string tension, which may lessen the buzz temporarily - but it is not a repair, and the candidate should say so rather than pretend the problem is solved.
3. Write a short maintenance and performance plan for the six days, including what to check on the exam day itself.

A day-by-day plan should separate repair, settling and rehearsal:
- Day 1: mute taraf, run the diagnostic sequence, change the Pa string, clean the groove lightly, record a short video of the buzz before and after for comparison.
- Day 2: retune three times; play slow open-string exercises and check meend on Dha. If the buzz persists, try a different Pa string gauge rather than filing the bridge.
- Day 3: full rehearsal of the Yaman item at exam tempo; check taraf tuning against the raga's scale. Yaman requires tivra Ma, so the taraf set must include that pitch.
- Day 4: rehearse the Jhaptal composition and the tihai with the tanpura at C; note any string that drifts.
- Day 5: rest the instrument, light playing only; pack spare strings, a peg winder, a soft cloth and silica gel.
- Day 6 (exam day): tune at home, then re-tune at the venue after 20 minutes of acclimatisation. Check the bridge seating, the taraf tuning and the peg tightness. Play a two-minute warm-up before the call.
The plan should also include a fallback: if the buzz returns under the exam lights, the candidate can reduce right-hand attack near the bridge and choose a phrase that avoids the worst spot, but should not stop to repair the instrument on stage. The judgement being tested is that a candidate must distinguish a maintenance problem that can be improved from one that needs a craftsman, and must not sacrifice a stable instrument for a risky last-minute adjustment.
