The singer, or vocalist, sings the vocal parts in the music. The lead singer is the main focal point of the song for the listener. Whether in the recording booth or on a live stage in concert, the singer’s job is to deliver the song melody and lyrics to the audience. Background singers must blend their voices and sound to support the music. Singers may also use dancing and movement as a part of their stage performance. Some singers play instruments such as guitar or piano to accompany their vocal performance.
