A Little Night Music: The Music of Crickets

Here is an amazing bit of music I came across on the internet. We all know what crickets sound like, right? They are the soundtrack of our summer evenings. In this recording, someone slowed the cricket sounds down, and discovered that they sound like a choir singing. There are beautiful harmonies, all created by the crickets!

As they explain on the recording, you are hearing two tracks. One track is the crickets at the normal speed we usually hear them. The other track is the same crickets slowed down.
