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:
“I never knew anyone yet who got up at six who did anything more useful between that time and breakfast than banging a tennis ball up against the side of the house, waiting for the more civilized members of the party to get up.”
—Robert Benchley (1889–1945)
