The Mystery of the Music Cave

< p>In the village of Bellesta, Puno Province, Peru, there is a cave that plays music and sings. In the early morning, the "bursts of music" are melodious; at noon, the "beating of gongs and drums" is extremely lively; in the evening, the "melodious flute" alternates between high and low. If it rains continuously, the cave will perform a "female solo" with a delicate voice, which you will never tire of listening to. The local government has established this cave as a tourist spot, and there are many tourists visiting the cave every day just to hear the strange sound of the cave. Why does this hole produce such beautiful musical sounds? According to analysis, there must be holes or slits on the roof or the other side of the cave, through which air can circulate normally. Except for the different times of morning, noon and evening, the temperature of the outside air is different and the air in the cave forms wind currents with different speeds. Just like when playing a musical instrument, the pitch and part are related to the size of the hole and the speed of blowing. This is a conjecture. As for the actual topography of this cave and the principle of pronunciation and singing, further research remains to be done.

Since the 1930s, people have conducted many inspections of this cave. Some people threw countless red plastic particles into the cave, and then mobilized people to search for traces of those red plastic particles in many surrounding rivers and lakes; others sank tens of thousands of meters of rope tied with stones into the cave to measure its length, but To date, not a single expedition has been successful.
