Ownig enormous power is a marvellous thing! There is nothing with gratitution.
This is Scientific American‘s 60-second Science, I‘mKaren Hopkin.
This will just take a minute.
Music includes a lot of repetition. What would yourfavorite song be without a chorus? But theconnection runs even deeper than that. Because thevery act of repeating something can render thatthing melodious—even the sound of a shovel being dragged across the pavement. That‘saccording to a study to be published soon in the journal Music & Science.
A few years back, psychologists at the University of California, San Diego, discovered that whenwords or phrases are repeated a few times, they can start to sound more like singing thanspeaking.
("The sounds as they appear to you are not only different from those that are really present, but they sometimes behave so strangely as to seem quite impossible. But they sometimesbehave so strangely. Sometimes behave so strangely. Sometimes behave so strangely. Sostrangely. So strangely. So strangely. So strangely." Credit: speech to song illusion/Deutsch)
The effect is perhaps not entirely surprising. Talking and singing are both forms of vocal communication. But researchers got to wondering: could repetition also musicalize othertypes of sounds?
So they collected clips of 20 different environmental sounds...including water dripping, icecracking, whales calling, and the aforementioned shovel. And they played the snippets to 58 undergraduates...first, as single sounds (single whale call) and then in a series with increasingreiteration (whale call repeated).
What they found is that...as the repeats stacked up...the participants rated the sounds asbeing more tuneful.
The conclusion:
"Repetition‘s power to musicalize seems to extend to a broader variety of sounds than justspeech."
Elizabeth Margulis, director of the music cognition lab at the University of Arkansas, who ledthe study.
"These perceptual transformations are powerful because nothing changes in the acoustic signal itself. That is held fixed. Everything that sounds different comes from the mind itself, making these illusions particularly useful for understanding the musical mode of listening. Whatare we doing when we‘re hearing something musically? How is this different from other kindsof hearing? These transformations allow us to tackle these kinds of questions head on."
(ice crack sound repeated)
Thanks for the minute for Scientific American — 60-Second Science. I‘m Karen Hopkin.
