Yoselin Sanchez has been in chronic pain since she was born with cervical scoliosis. While little eases the discomfort, she's found ways to distract herself from hurting. She practices yoga. She performs free flow dance. And while she works, she frequently listens to house music tuned to 432 hertz. Music recorded in 432 hertz (cycles per second) is taking off on social media platforms and music streaming services, where users can find an increasing number of tracks and playlists employing the alternate tuning—everything from meditation soundscapes to reggae songs recorded by Ziggy Marley.
As the AP explains, throughout history, as people sang or played music together, they tuned their instruments to the same pitch to create a harmonious sound. Singers and musicians often chose a musical note—typically the A above middle C on a piano—as a reference point. The music genre known as "432 Hz" is characterized by its tuning, in which the A above middle C is pitch-adjusted to vibrate at 432 hertz instead of the standard 440 hertz. The lower frequency is noticeable to the naked ear, sounding like slightly lower notes. Some people feel the alteration produces a warmer, more harmonious sound that resonates with the human body and the natural world.
Scientists say there's no robust evidence that music tuned to 432 hertz has any special benefits or healing properties. Some musicians and listeners say it helps them connect with nature, relax, or concentrate. "There are frequencies going on right now that are higher than what we can hear and lower than what [we] can hear. And they're not special because they're one of the billions and billions of frequencies that we're receiving right now," said Susan Rogers, a Berklee College of Music professor emeritus who worked as Prince's sound engineer during the 1980s. "To set one aside and say that it is the frequency of the universe is, as far as the science community is concerned, nonsense." The AP has much more on the trend here.
