Robert Keith McFerrin Jr. (born March 11, 1950) is an American folk and jazz singer. He is known for his 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.

McFerrin’s song “Don’t Worry, Be Happy” was a No. 1 U.S. pop hit in 1988 and won Song of the Year and Record of the Year honors at the 1989 Grammy Awards. McFerrin has also worked in collaboration with instrumentalists, including the pianists Chick Corea, Herbie Hancock, and Joe Zawinul, the drummer Tony Williams, and the cellist Yo-Yo Ma.

McFerrin was born in Manhattan, New York City in 1950, the son of operatic baritone Robert McFerrin and singer Sara Copper. He attended Cathedral High School in Los Angeles, Cerritos College, University of Illinois Springfield (then known as Sangamon State University) and California State University, Sacramento.

His mother Sara (Copper) McFerrin was a soloist and taught voice at Fullerton College in Southern California. McFerrin’s first recorded work, the self-titled album Bobby McFerrin, was not produced until 1982, when McFerrin was already 31 years old. Before that, he had spent six years developing his musical style, the first two years of which he attempted not to listen to other singers at all, in order to avoid sounding like them. He was influenced by Keith Jarrett, who had achieved great success with a series of solo improvised piano concerts including The Köln Concert of 1975, and wanted to attempt something similar vocally.
