The bowl arrives, you strike it, and it makes a short flat clonk that stops almost immediately. Nothing like the sound in the shop or the class. Almost everybody has this experience and almost nobody has a faulty bowl.
Four things kill the sound of a singing bowl, and all four are fixable in the next ten minutes.
You are holding it wrong
The most common cause by a distance. A bowl produces sound from the vibration of its wall, and anything touching that wall stops the vibration.
The instinctive grip is to hold the bowl around the sides with fingers wrapped over the rim, which is precisely where the movement is greatest. That grip damps the bowl almost completely.
The correct hold is flat on an open palm, with fingers straight and slightly apart, supporting only the base. If you need more security, keep fingertips low on the wall near the base and away from the rim entirely. The difference between the two holds is immediate and dramatic.

The bowl is sitting on something hard
Same principle applied to furniture. A bowl resting directly on a wooden table, a stone hearth or a glass top is in contact with a large rigid mass, and the vibration drains straight into it.
This is what a hoop cushion is for. It supports the bowl at the base while isolating it from whatever it stands on, which is why every bowl in a shop sits on one.
Size matters here more than people expect. Cushions are matched to bowl diameter, from an 8cm cushion for bowls of 10 to 12cm up to a 24cm cushion for bowls over 26cm. Too large a cushion touches the wall of the bowl and damps it, which defeats the purpose entirely.
The striker is wrong for the bowl
The second commonest cause and the cheapest to fix.
A striker too light for the bowl cannot deliver enough energy to move that much metal, so you get a tap rather than a tone. A striker whose contact surface has worn smooth has too little friction to maintain rimming, so the bowl chatters or refuses to sing at all.
Match striker to bowl weight. Small bowls around 550g suit something like the 13cm classic striker. Medium bowls of 800 to 900g want the 19cm large classic. Large heavy bowls need the mass of a 22cm king striker.
If a striker has gone shiny where it meets the bowl, light sanding restores the grip and costs nothing.

You are rimming too fast
Everybody does this at first. The instinct is that going faster will make the sound louder, and the opposite is true.
Rimming works by a stick slip mechanism: the striker grips the wall, drags it slightly, releases, and grips again, hundreds of times a second. Too fast and the striker skids without gripping, producing a rattle rather than a tone.
Go slowly. Slower than feels productive. Press with steady moderate pressure, keep the striker angled slightly outward against the wall rather than straight down, and complete a full circuit in around three or four seconds. Once the tone establishes, you can ease off and it will keep going.
The room is working against you
A minor factor but real. A room full of soft furnishings absorbs the higher partials quickly, which makes a bowl sound duller than it does in a hard walled shop.
Try the same bowl in a hallway or a kitchen and you will usually hear considerably more. That is the room rather than the bowl, and it is worth knowing before you conclude you bought badly.
Residue on the rim
Easily missed and instantly fixed. Oil from hands, dust, or any cleaning product left on the rim or on the striker prevents the friction that rimming depends on.
Wipe both with a dry cloth and try again. This alone solves a surprising proportion of cases where a bowl has stopped singing after months of working fine.
When it genuinely is the bowl
Rare, but it happens. If you have worked through everything above and the bowl produces a short buzzing thud rather than a clear note, test it properly: hold it by the very edge of the rim so it hangs almost free, and tap gently. A sound bowl rings clearly; a cracked one buzzes and dies.

Questions people ask
Why does my singing bowl not ring?
Almost always because something is damping it. Fingers wrapped over the rim, or the bowl sitting directly on a hard surface, stop the wall vibrating. Hold it flat on an open palm and rest it on a cushion.
How should I hold a singing bowl?
Flat on an open palm with fingers straight and slightly apart, supporting only the base. Never wrapped around the sides or over the rim, which is where the vibration is greatest.
Why does my bowl rattle when I rim it?
You are going too fast. Rimming works by the striker gripping and releasing hundreds of times a second, and speed causes it to skid instead. Take three or four seconds per circuit.
Does the cushion actually matter?
Yes. It isolates the bowl from the surface so vibration is not drained away. Match the cushion size to the bowl, since one too large touches the wall and damps it.
My bowl worked before and now it does not, why?
Check for residue on the rim and on the striker, and check whether the striker has worn smooth. Both prevent friction and both are solved with a dry cloth or light sanding.
