A club singer, sometimes known as a lounge singer, is a professional singer who sings in nightclubs and lounges. Typically, these singers perform music that is appropriate for the situation. For example, a club singer may perform popular hits in a nightclub, whereas, in a lounge, a singer may perform jazz standards or novelty tunes. Some opera companies require opera singers to have a music degree, such as a bachelor’s degree in music. This type of performer can sing solo or group when performing in an opera. They may even take on the role of a character.
