I experience music looping in my head on a regular basis, and I’m sure you can think of several times this has happened to you. I’m also a self-taught musician, having learned to play guitar by ear from an early age through careful listening, so, I have a hunch my brain is more active in the “melody-analysis” area, and that I’m prone to experiencing this more often (or at a higher volume) than others. This doesn’t affect my life in any huge external way — I carry on productively and engaged in most any situation. But in a moment of relative quiet, the internal soundtrack often cranks right up.
But Isn’t That What Vocal Hooks Are For?
I’ve found it’s usually key phrases from songs that stand out — like dramatic flourishes or expressive riffs. It’s not always the “pop hook” or vocal element that grabs me, and it can be any obscure track from any time in history, of any genre, not just so-called “popular” music specifically music designed to lodge itself in the brain.
And then, after a few hours… it’s gone. Maybe I’ve made an effort to listen to the track somehow and exorcise its hold on my spirit. Or, what was there before just gets replaced by another track.
Why Does This Happen?
Perhaps as early human cave dwellers, the ability to memorize sound served an evolutionary purpose. Hearing a growl in the distance might have prevented being eaten by a bear, so that would have been a good sound to repeat into memory for an advance warning next time. Or maybe hoofbeats in the distance signaled a tasty herd of beasts just over the ridge. I’m totally guessing, but it’s not implausible given what we understand about the fight-or-flight response.
What Do You Do?
I really wonder if there’s a course of action here. Is there some type of “resolution” or lesson to be learned — or does there even need to be? What purpose does having a song stuck in your head actually serve?
