Koshi Chime String is Twisted or Tangled
Aug 15, 2025
A Koshi or Zaphir chime that produces no sound at all, despite being placed in adequate air movement, almost always has a tangled inner string. The small ball that normally hangs freely at the centre of the tube has become wrapped around one or more of the eight metal rods and is locked in place. Since the ball cannot swing, no rods are struck and the chime is silent.
This is not a defect and it is not permanent. The fix takes under two minutes and requires no tools.
The Difference Between Twisted and Tangled
These two issues have different causes and slightly different fixes, so it is worth distinguishing them first.
Twisted cord refers to the top hanging cord that connects the O-ring to the bamboo tube. When this cord is twisted, the chime hangs at an angle and may ring unevenly, but it will still ring. The ball inside is free. The fix involves rotating the bamboo cross-bar inside the top of the tube. This is described fully in the separate article on Koshi chimes string not hanging straight.
Tangled inner string refers to the cord that runs through the interior of the bamboo tube from top to bottom, with the ball at its lower end. When this cord is tangled, the ball is caught between the rods and the chime produces no sound at all. This is the issue this article addresses.
In some cases, both problems exist simultaneously: the cord is twisted at the top and the ball is tangled below. Fix the tangle first, then check the cord alignment afterwards.
Why Does Tangling Happen?
The inner cord runs from a fixed point at the top of the tube, down through the centre of the rod assembly, and exits at the bottom with the ball and wind catcher attached. The cord has a small amount of length relative to the tube interior, which allows the ball to swing in an arc. Under normal use, the ball swings freely and gravity keeps it centred.
Tangling occurs when the chime is tilted too far, rolled, spun, or stored in a compressed position. Any of these actions can cause the ball to swing up and over a rod and come to rest on the far side, with the cord looped around the rod. Once one loop forms, subsequent movement often adds another, until the ball is locked against the tube wall with the cord wound around several rods.
The most common causes: placing the chime flat on a surface during storage, winding the cord around the chime for transport, excessive spinning during installation, or shipping in a tight box where the chime was inverted and moved.
How to Fix a Tangled Inner Ball: Step by Step
Step 1: Hold the Tube Vertically, Bottom Upward
Hold the bamboo tube with the open bottom end facing upward. This is the opening where the inner cord and wind catcher exit. Gravity will pull the ball downward (toward what is now the top in your hand, since it is inverted), which may be enough to loosen some of the tangle before you intervene.
Look down into the opening. You should be able to see the metal rods arranged in a ring inside the tube and the inner cord among them. If the ball is visible and clearly wrapped around one or more rods, you can see exactly what needs to be freed.
Step 2: Gently Insert a Finger or Thin Object
Insert a thin finger through the bottom opening alongside the inner cord. A pencil or thin dowel can also be used if the space is tight. The goal is to make contact with the cord or ball and gently guide it away from the rods it is tangled around. Do not force anything. The rods are fixed at the top of their assembly and will not be damaged by gentle contact, but aggressive prodding can cause the cord to tangle further.
Work slowly: lift the ball slightly, determine which rod the cord has looped around, and guide the cord back under that rod toward the centre. In most cases, one or two rods are involved and a single deliberate movement is enough to free the ball.
Step 3: Let Gravity Complete the Job
Once the ball appears to be free, keep the tube vertical (bottom still up) and gently tilt the chime slowly to one side to allow the ball to drop straight. You will often hear it clink lightly against a rod as it settles into its natural hanging position at the centre of the rod assembly.
If the ball does not settle freely, repeat Step 2: there is likely still a loop of cord around a rod that is preventing the ball from reaching its natural centred position.
Step 4: Hang and Test
Return the chime to its normal orientation (hanging from the top cord) and let it hang still for a few seconds. Then gently tilt it to one side and release. You should hear the characteristic cascading sound of the ball striking the rods as it swings. All eight rods should ring in sequence, producing a full, even harmonic phrase.
If only some rods ring, the ball may still be partially constrained. Repeat the process.
If the chime rings but sounds uneven or lopsided, the outer top cord may also have a twist. Check the cord alignment as described in the string not hanging straight guide.
How to Re-Thread the Cord If It Has Come Out Entirely
In rare cases, the inner cord may come out of the tube entirely, usually because the ball has been pulled through the bottom opening. If this happens, re-threading is possible but requires patience. The cord must run from the anchor at the top of the tube, down through the central space between the rods, and exit through the bottom opening with the ball tied at the end. The ball knot must be large enough that it cannot be pulled back up through the rod assembly.
Use a length of thin, flexible wire or a straightened paper clip as a threading guide. Attach one end of the cord to the guide wire, insert the wire from the bottom of the tube up through the rod cluster, and feed the cord up until you can attach it to the fixed point at the top. Tie the ball securely at the bottom end, ensuring the cord length allows the ball to hang just below the bottom opening of the rod cluster, where it can swing freely in all directions without the cord going taut prematurely.
What If the Rods Have Shifted?
In rare cases, particularly with very old chimes or those that have been subjected to strong physical impact, one or more rods may have shifted from their intended position. Signs of rod displacement: a persistent dead note (one position in the ring produces no sound regardless of how the ball swings), an audibly sharp or flat note compared to all others, or a visible gap or misalignment in the rod arrangement when you look into the bottom of the tube. Rod displacement is not a user-serviceable issue. Contact the original retailer for assessment.
Preventive Storage and Handling
- Store the chime hanging from a hook, not lying flat. A horizontal position allows the ball to rest against rods under its own weight, which begins the tangling process over time.
- If storing in the original box, ensure the inner cord and wind catcher are positioned straight inside the cardboard insert. Do not push the wind catcher cord against the side of the box.
- Never wind the cord around the tube for transport. Coil the cord loosely alongside the tube and secure it with a loose cable tie or twist tie.
- When demonstrating the chime, tilt it gently rather than spinning it. Spinning introduces the cord loops that cause tangling.
- If the chime has been in storage for a long period, check the inner ball position before hanging: invert the tube briefly and look in before committing to a hanging position.
Does This Apply to Zaphir Chimes?
Yes. The internal mechanism of a Zaphir chime is essentially the same as a Koshi: a ball on an inner cord that swings to strike the metal rods. The tube material is different (cellulose rather than bamboo) but the fix is identical. Hold the Zaphir tube inverted, insert a finger or thin pencil through the bottom opening, locate the ball, guide it free of any rod loops, and test by hanging and tilting.
