A singer uses their voice to create music and convey emotions through lyrics and melody. Singers can specialize in various genres, such as pop, rock, country, jazz, opera, and classical music. Singers are essential components of musical ensembles, such as bands, choirs, and orchestras, or they can perform solo on stage or in a recording studio. Singers need to have excellent vocal skills, including pitch, range, control, and expression, as well as a good ear for music and the ability to read sheet music or lyrics. They also need to be comfortable performing in front of an audience and have stage presence and charisma to engage and entertain their listeners.
