Our friends at Futility Closet wrote this post about the Speech-to-Song Illusion:
In 1995 UCSD psychologist Diana Deutsch was fine-tuning the spoken commentary on a CD when she noticed something odd. When the phrase “sometimes behave so strangely” was repeated on a loop, it came to sound as though it were being sung rather than spoken. When the full surrounding passage was then played in its entirety, this phrase still sounded as though it were being sung (you can hear this here).
The phenomenon is not completely understood, but “the present experiments show that for a phrase to be heard as spoken or as sung, it does not need to have a set of physical properties that are unique to speech, or a different set of physical properties that are unique to song,” the researchers write. “Rather, we must conclude that, assuming the neural circuitries underlying speech and song are at some point distinct and separate, they can accept the same input, but process the information in different ways so as to produce different outputs.”
The first few times I heard the narrator say "sometimes behave so strangely," I heard it as speech. Now, it is impossible for me to hear it as anything other than singing.

There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
