Robert Keith “Bobby” McFerrin, Jr. (born March 11, 1950) is an American vocalist and conductor. He is best known for his 1988 hit song “Don’t Worry, Be Happy”. He is a ten-time Grammy Award winner, who is known for his unique vocal techniques, such as singing fluidly but with quick and considerable jumps in pitch—for example, sustaining a melody while also rapidly alternating with arpeggios and harmonies—as well as scat singing, polyphonic overtone singing, and improvisational vocal percussion.
