A mysterious boulder can make beautiful music! What kind of secrets are hidden inside this boulder?
"Singing" rocks
In the desert area of California, usa, inhabited by many Indians, there is a huge rock, almost the size of several houses. Whenever a round moon rose in the sky, the Indians came to the rock one after another, lit a bunch of bonfires, bowed to the boulder, and then sat quietly on the ground... The campfire burned and rose
A thick cloud of smoke, and before long, the smoke enveloped the boulder tightly. At this moment, the boulder slowly emitted a series of charming musical sounds, sometimes euphemistic, like a beautiful lyrical serenade; sometimes a mournful low, like a low sad song.
Sound rocks
Also in Georgia, usa, there are rocks that emit sound, and people call it "sound rocks." These sounding rocks are not only able to make sounds, but these sounds are like beautiful pieces of music. If people gently hit the rocks here with small hammers, whether it is a large rock or those small pieces of rubble, it will make a very pleasant sound. This wonderful sound is not only beautiful, but also particularly crisp, like a jingling spring flowing down from a high mountain, which makes people immersed in it and intoxicated physically and mentally. What's even more amazing is that these rocks can only be beaten to pleasant music in this place. Someone once experimented with moving the rocks here elsewhere, and no matter how you beat them, they couldn't make that beautiful sound.
