A cantata is a vocal composition with an instrumental accompaniment, typically in several movements, often involving a choir. The meaning of the term changed over time, from the simple single voice madrigal of the early 17th century, to the multi-voice "cantata da camera" and the "cantata da chiesa" of the later part of that century, from the more substantial dramatic forms of the 18th century (including the 200-odd church and secular cantatas of Johann Sebastian Bach) to the usually sacred-texted 19th-century cantata.
