Lead vocalist

The lead vocalist, lead vocals or lead singer in popular music is typically the member of a group or band whose voice is the most prominent in a performance where multiple voices may be heard. The lead singer either leads the vocal ensemble, or sets against the ensemble as the dominant sound. In vocal group performances, notably in soul and gospel music, and early rock and roll, the lead vocalist takes the main vocal part, with a chorus provided by other group members as backing vocalists.

Especially in rock music, the lead vocalist or solo singer is often the frontman or frontwoman, who may also play one or more instruments and is often seen as the leader or spokesman of the group by the public. As an example in rock music, Mick Jagger is the lead singer of The Rolling Stones. Similarly in soul music, Smokey Robinson was the lead singer of The Miracles.

It is uncertain when the term "lead vocals" was first used, but it may have emerged in the late 1930s, when rich vocal interplay with multiple voices where one or more voices may dominate began to impact on North American popular music, which was previously dominated by solo vocals. The practice of using a lead singer in vocal groups, however, has a longer history: an early form is the "call and response" found in work songs and spirituals sung by African-American slaves. Songs of the late nineteenth century frequently used a leading solo voice (or "call"), followed by a choral response by other singers. As the style developed through early commercial recordings and performances in the early twentieth century, the role of the lead vocalist became more established, although popular groups of the 1930s and 1940s such as the Ink Spots and the Mills Brothers generally used different lead singers on different songs rather than keeping the same lead singer throughout. By the 1950s, singers such as Sam Cooke (with the Soul Stirrers) and Clyde McPhatter (with the Drifters) took on more clearly defined roles as lead singers, and by the end of the decade credited group names often changed to reflect the leading roles of the main vocalists, with examples such as Frankie Lymon & the Teenagers and Dion & the Belmonts.
