What is a background singer?

Background singers, also known as backup singers, are vocalists who support the lead singer or main performers by singing harmonies, backing vocals, or additional musical lines during a performance or recording. Their role is to enhance the overall sound, add depth to the music, and sometimes fill in for the main melody when needed. Background singers may perform live on stage, in the studio, or both, and they often work across various genres such as pop, rock, R&B, and gospel.
