The bouncing ball is a device used in video recordings to visually indicate the rhythm of a song, helping audiences to sing along with live or prerecorded music. As the song's lyrics are displayed on the screen, an animated ball bounces across the top of the words, landing on each syllable when it is to be sung.
Famous quotes containing the word ball:
“When Adam delved and Eve span,
Who was then the gentleman?”
—John Ball (hanged 1381)
