A Singer sings the main vocal line of a track. He or she is the main focus of the performance, in contrast to a band, which has regular members who tour, record, and generally play equal roles in a performance together. Some Singers back themselves up on piano or guitar, whereas some focus more on dancing and performing, and leave the rest to a backing band. Singers record albums of songs that they have written or that have been written for them by a production team, and then tour to promote the album. Their days are spent in studio, on tour, and practicing vocal, instrumental or dance skills.
