Bobby McFerrin

Robert Keith "Bobby" McFerrin Jr. is an American jazz vocalist and conductor. A ten-time Grammy Award winner, he 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. He is widely known for performing and recording regularly as an unaccompanied solo vocal artist. He has frequently collaborated with other artists from both the jazz and classical scenes.
