All cultures seem to have at least one thing in common—they write music and sing. But why? Music baffled the evolutionist, Charles Darwin. Humanity’s ability to produce and enjoy melodies, he wrote in 1874, “must be ranked amongst the most mysterious with which he is endowed.”

All human societies made music, and yet, for Darwin, it seemed to offer no advantage to our survival. He speculated that music evolved as a way to win over potential mates. Other scientists were skeptical. That debate continues to this day. Some researchers are developing new explanations for music. Others maintain that music is a cultural invention, like writing.

In recent years, scientists have analyzed the acoustic properties of thousands of songs recorded in dozens of cultures. One researcher offered the following guess for why we sing: “Maybe music was needed to improve group cohesion.” Or maybe sharing choruses and melodies, could have brought people together whether as a community or in preparation for a battle. Or maybe it helped parents bond with children.

Possible Preaching Angle:

The fact is, these are all guesses, but the Christian knows the best reason for singing—because the Living God is worthy of our joyful worship. He puts a new song in our mouth.
