ENVIRONMENTAL CHANGES – It is important not to expose your 

harmonium to extreme temperatures or moisture. The wooden parts of the 

harmonium can react to changes in moisture and temperature and may cause 

the reeds to buzz, or parts to stick, jam, or worse.
BUZZING REEDS – Sometimes simply playing a reed over and over will 

eliminate the buzz. If that does not work you may have to open the harmonium 

to view the reeds. On the front of the Harmonium, under the keyboard, is a 

hinge. The entire top of the harmonium will lift up to reveal the reeds and air 

chambers. Again each harmonium is different so do not force the top up, look 

for hinges, screws or levers that may need to be opened before the top can be 

lifted or slid off.
With the harmonium opened, find the offending reed and loosen the screws on 

the reed. You do not need to remove the reed, just loosen it. Reeds stick to the 

wood and if the wood expanded or contracted, the reed may be experiencing 

torque. Loosen and lift the reed slightly, then retighten it. Also look for any small 

bit of debris. Any small bit of wood dust in a reed will cause it to buzz. Clean 

them carefully, reeds can be easily bent and then they may not work. 
FALLEN OR STICKING KEYS - Under the Cover you 

will see the back of the keys, which are held in place by 

a wire arm.  The wire acts as a spring to push the key 

up after you depress it.  During transport these wires 

can slide off.  If your key has fallen and can’t get up, 

move the spring back into place.  
If the wire spring is in place and your key sticks or 

stays down, the wood may have expanded. If this 

happens slide a piece of sand paper back and forth 

between the keys, just enough for the keys to operate 

freely.
STUCK PULL KNOBS - Do not force a stuck knob. Open the top of the 

harmonium to look into the air chamber. Each knob is attached to a block of 

wood that slides between two wooden rails. If the block swells the knob will 

stick. There is a graphite powder, available at hardware stores, which acts as a 

form of dry lubrication. Use it sparingly. If that fails you may need to take the 

block out from between the rails and then very lightly sand the sides. You do not 

want the block to wiggle between the rails. The block slides over a hole to close 

off air flow. If the block is loose in the rails you may have an air leak.
