A singer is an artist or performer who crafts a vocal song using various techniques and training. Singers often practice daily and will hire professional voice coaches to help them hone their craft. 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.
