Hi! I love your videos, and they are so helpful! Do you have any advice about how to fix buzzing xylophone bars? The resonator boxes seem to be in good shape.

Hello Jennifer! The bars should be tested on another resonator box to ensure it’s not the box that’s buzzing. A buzzing sound in a bar is extremely rare, and would indicate that the bar is cracked. If you find a crack try blowing wood glue into it with a straw. Clamp the bar from side to side with a furniture or C clamp. Wipe off the excess glue. Allow 24 hours to dry. If this is not successful I would recommend replacing the bar, which can be ordered through your favorite retail partner. – “Doctor” Lissa and your friends at Teaching With Orff

There are a couple of things that might be causing the buzzing. It’s either loose hardware or a crack or loose joint in the box. Try to determine the source but pressing the bix together from different sides while playing it if the pressure stops the buzzing sound then it’s a problem with the box. We’ll get back to that later. To find out if it’s loose hardware remove the bar. Then reach into the box and find the nuts on the inside. If one of them is loose you can probable hand tighten it.
Once I was called in to a friend’s school for this problem and one of the nuts had fallen inside the box and was causing a buzz. The sound disappeared after it was put back in place.
To fix a crack in the resonator box – or a loose seam- gently ply apart the wood with a screwdriver. Apply wood glue. Using a drinking straw blow it into the crack. Wipe off excess glue. Clamp with a bar or trigger clamp or wrap a strap around it and tighten. Allow 24 hours to dry.
