Definition & Meaning of "voluntary"

What is a "voluntary"?

A voluntary is a musical composition, typically for organ, played during church services, often before or after the main parts of the service. It is designed to provide an uplifting or reflective atmosphere and may vary in style and length. The voluntary can serve as an introduction to the service or as a closing piece, and it is often performed during moments when there is no other specific music or when the congregation is entering or leaving the church.
