Bobby McFerrin

Robert Keith McFerrin Jr. (born March 11, 1950) is an American improvisational vocal musician, singer, songwriter, and conductor. His vocal techniques include 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. McFerrin performs and records regularly as an unaccompanied solo vocal artist and has frequently collaborated with other artists from both the jazz and classical scenes. McFerrin's song "Don't Worry, Be Happy" is the only a cappella track to ever reach No. 1 in the US, which it reached in 1988 and additionally won Song of the Year and Record of the Year honors at the 1989 Grammy Awards. He has also worked in collaboration with jazz fusion instrumentalists including pianists Chick Corea (of Return to Forever), Herbie Hancock (of The Headhunters), and Joe Zawinul (of Weather Report), drummer Tony Williams, bassist/vocalist Richard Bona and cellist Yo-Yo Ma.
