The “millennial whoop,” as named by musician Richard Metzger, is a sound caused by a shift from the fifth note in a scale to the third, and then back to the fifth.  “Music, especially pop music, is based on patterns,” Quartz says. “It makes new songs feel familiar because you’ve basically heard them before.”

Though they note that “the whoop” isn’t a new trend—it's found in everything from Beethoven’s Concerto No. 5 to Twenty One Pilots' “Ride.”

“This is a very specific interval and sound that has become incredibly common over just the past few years,” says the video.
