Bird Song: Music
The most famous four notes in classical music may have been taken from the song of a bird. Just listen.

To the human ear, frogs "croak", dogs "bark" and wolves "howl". But when birds make sounds, we call it singing. I'm Jim Metzner and this is the Pulse of the Planet, presented by DuPont.

"Birds have two vocal organs whereas we have only one. And the remarkable thing is birds can control each one of them separately. Very often birds can sing two unrelated songs at the same time."

According to Luis Baptista, former chairman and curator of ornithology at the California Academy of Science, bird song appeals to us because it has much in common with human music.

"For one thing, interestingly, scholars have actually found birds that sing using some of the more familiar musical scales of human music. For example, the hermit thrush actually sings in the pentatonic scale, which is the scale of Japanese and Chinese music.

"Another scholar showed that the wood thrush of eastern North America sings in the diatonic scale, which is a scale used in Western music."

Many birds have songs that are structured like a sonata, providing just enough repetition and variation to be pleasing to the human ear. Some composers, such as Mozart, have incorporated specific bird songs into their work. And as Luis Baptista was fond of observing, the White-breasted wood wren may have been the inspiration for Beethoven's Fifth Symphony.

This week's series of programs on bird song is dedicated to our friend Luis Baptista, an esteemed scholar of birds, who passed away recently. Pulse of the Planet is presented by DuPont, bringing you the miracles of science, with additional support provided by the National Science Foundation. I'm Jim Metzner.
