Vocal coaches may give private music lessons or group workshops or masterclasses to singers.
This enables 2000s-era producers and audio engineers to in order to make an untrained performer's singing sound closer to that of a trained vocalist.
Some vocal coaches, for example, are rehearsal pianists with decades of experience accompanying singers, or former or current choral, music theater, or symphony conductors.
For example, a specialist in Alexander Technique, yoga, or medical aspects of the throat and vocal cords may begin to specialize in coaching and training singers.
While a small number of top vocal coaches can command very high hourly or daily rates, most vocal coaches, like most other music and arts professionals, tend to have salaries which are below the average for other professions which require a similar amount of education and experience, such as economists or bank managers.
In universities, for example, it would be rare to have a professor of voice refer to themselves as a vocal coach, even though they may teach private lessons.
