But the singer’s most delicate and irreplaceable apparatus is the larynx, the object of immense care and constant torture. Like everything else in the body, that agile apparatus tends to lose its powers over time. The Singer, or Vocalist, sings the vocal parts in the music, and 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. This might also include dancing, or stage movement, and some Singers also play instruments such as guitar or piano to accompany their vocal performance.
