Backing Vocal

和声 (Backing Vocal, also known as Background Vocal) is a vocal role used to support the lead vocalist. It can form 和声 at different pitches and may take the form of unison singing, call-and-response, lyric repetition, ad-libs, shouts, and sustained notes; its function is not limited to the narrow definition of “singing 和声 intervals.”

Backing vocals can be performed by dedicated 和声 singers, band members, the lead vocalist themselves, or a choir. In recording, a single singer often layers multiple takes to create a choral effect; during live performances, parts are distributed among multiple singers. The number of 和声 heard in the final recording does not necessarily equal the number of actual participants. The relationship between the lead vocalist and 和声 is functional at the song level. The boundaries between these roles can shift depending on the arrangement—for example, the same person might take the lead in one section and provide backing vocals in another, or several singers might collectively form the main vocal part during a chorus. If the credit listing simply states “vocals,” it should not be arbitrarily split into “lead” and “backing” without supporting evidence.

“Choir” or “chorus” is sometimes credited as an independent group; their performance may constitute backing vocals or serve as the main element of the piece. Vocal samples, vocoders, and synthesized vocals can also produce background parts, but whether they are credited as singer contributions depends on the actual recording process and the credit system.

Chinese releases often translate “backing vocals” as “和声” or “伴唱.” “和声编写” refers to the creative or arranging work involved in designing the vocal parts, which may be performed by a vocal arranger; this role should not be conflated with that of the actual performer.
