The chart visualizes two recordings of the English folk song “Scarborough Fair”—one sung, one spoken—by Patrick Savage, a study author and participant. The song unfolds at around half the speed of the spoken version, and its pitches are generally higher. They are also more stable, being centered on fixed musical notes, but with added expressive pitch fluctuations such as scoops and vibrato. In contrast, the spoken performance never settles on a pitch for long.
