Brazilian composer Jarbas Agnelli was reading the newspaper one day, and saw a photo of birds on electrical wires. Inspired by the similarity to musical notes, he cut out the photo and began composing a song based on the positions of the birds. He recorded the song and sent it to the photographer, who loved it. Soon there was a newspaper article about it, and the song became a worldwide sensation. Below is a music video he made of the song, using the photograph.
Also, here is a link to a TED talk where the composer talks about the composition and performs it live. He says the lesson he learned from all this is that it is “possible to see poetry anywhere, depending on the way we look at things.” He’s absolutely right.
