“Birds do it, bees do it, even educated fleas do it;
Let’s do it, let’s fall in love.”
Cole Porter was wiser than he knew. Insofar as love songs and “territorial” songs are concerned, we do as the birds do. From The Scientist’s “Behavior Brief:”
Courtship songs of chestnut-sided warblers appear relatively stable over evolutionary time compared to those used for territorial displays, which have changed considerably over the course of two decades, researchers found, suggesting the presence of two distinct traditions in song bird “culture.”
Isn’t that the case with humans as well as birds? While each generation contributes its own songs to the ouevre, certain love songs continue to appeal decades and even centuries after composition: Someone to Watch Over Me, I’ll Be Seeing You, and of course the evergreen Greensleeves all have strong followings beyond their generations, from people born long after they showed on the scene.
In contrast, highly specific genre songs which help define cultural “territories” such as metal, punk, gangsta rap, indie, bluegrass, and others, frequently hold less appeal over time, even within the groups in question. Perhaps simple, cross-genre love songs are more likely to have lasting appeal simply because the audience is larger – but perhaps that’s because they engage on a more universal level.
P.S. On a related note, we should probably all stop using bird-brained as a derogatory term.
