Singers may write their own music or sing music written by others. In addition to singing, singers may work as music teachers or voice coaches. 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.
