A buzz on a kalimba is almost always a small thing touching another small thing. The trick is to find which one before applying force, because the fix that works is usually the gentlest one. Work through these in order and stop as soon as the buzz is gone.
01 Find where it comes from
Pluck the tine that buzzes while resting a finger lightly on its neighbours. If the buzz stops, a neighbour was ringing along or touching. If it stays, look at the instrument itself: a loose pickup jack, a screw on the pressure bar, a label peeling on a tine, or the kalimba resting on a surface that rattles. Try it held in your hands before blaming the tine.
02 Nudge and centre
Without bending it, nudge the tine a fraction left and right where it rests on the bridge. Tines can creep sideways in shipping until two almost touch or one sits unevenly on the bridge. Return it to even spacing with its neighbours, then pluck again. If you slide it along its length by accident, retune it afterwards — see the tuning guide.
03 Clear the bridge
Dust or a fleck of finish between the tine and the bridge can stop it seating cleanly. Lift the tine only enough to slide a narrow strip of clean office paper between tine and bridge, draw it through once, remove it and retest.
04 Stop before force
If the tine looks twisted, or it still buzzes after the steps above, stop. Spring steel scars and fatigues if you twist it with pliers, and a bent tine rarely comes back clean. Follow the maker's repair procedure, contact the seller, or ask a technician.
05 Keep it from coming back
Store the kalimba in its bag or case, away from heaters and damp. Pluck with the corner of the nail rather than pressing down into the tine, which can push it out of place over time. After travel, run a quick scale and fix any buzz while it is still a small one.

Questions
Why does one kalimba tine buzz?
Most often it is touching something: a neighbouring tine, loose hardware, grit at the bridge, or it has slid off-centre so it sits unevenly. Isolate the buzz by muting the neighbours before you move anything.
Can I fix a buzzing kalimba myself?
Usually, yes — nudging a tine back to even spacing or clearing the bridge with a strip of paper solves most buzzes. If a tine sits visibly twisted, or still buzzes after that, use the maker's repair procedure or a technician rather than pliers.
Is a buzzing kalimba defective?
Not necessarily. Small buzzes are common after shipping and are usually a spacing or debris issue. A buzz that returns straight after every fix, or a cracked body or bridge, is worth raising with the seller.
