At first blush I thought maybe it would become a sound wave formula or something. I had to turn the volume up a bit more before I figured it out.
There’s a thing in biomusicology called entrainment, it’s the unconscious synchronization to an external rhythm. So if you’re listening to music your breaths might unconsciously synch to the beat. Or you might write in synch with the melody.
Of course you can do so consciously, too.
