Professional singers have typically had a lot of training, are highly talented, and have an excellent ear for identifying tone and pitch. They also possess a certain level of natural singing ability including a wide vocal range or pleasant vocal resonation. Singers often freelance and are contracted on a per job basis, either as a singer or as a consultant or judge in singing competitions. Singing is an accepted art form that is taught in most public and private schools. It can also be a fun activity and be casual entertainment, such as karaoke. Professional singers may be employed by a record label that finances the development and recording of their music. Other singers may be employed by companies including radio advertising firms and variety show theatres.
