Yesterday I noticed a group of different varieties of birds singing in the trees surrounding me. As I listened more carefully, I could tell each one had a unique song, with different resonances, frequencies and overtones. This was beautiful, but then I realized they were coordinating their songs in a specific way. And it almost seemed as if they were intentionally creating a three-dimensional space defined by sound. So I had to draw this, as my description was not adequate to convey what seemed possible.
