You may find this interesting as we are all interested in the resonant qualities of wood and acoustics generally. What about stones which are not of the rolling kind?
There are more than 100'000 (much more) ancient stone circles in southern Africa which are build of stones which ring like a bell or sound like piano keys when struck.
The age of these circles is be between 25'000 and 300'000 years (according to the people who actually bother to investigate them in any depth) but main stream archaeology has said they are only about 300 years old (without much investigation). For anyone interested in the countless ancient anomalies around the world, that will sound familiar as main stream science simply ignores or discounts everything which does not fit the current model and these things become taboo and people even lose their jobs, reputations and careers if they even investigate these anomalies.

So this story has many layers of fascination for those who are curious. But if you just want to hear stones which ring like a bell check out:

Well the link doesn't seem to work now. Spooky! There must be something in there that someone didn't want us to see. Oh well.

Maybe the use of carrier pigeons in Australia for the last mile having an adverse effect on bit speed!

I just tried it now and it worked:
