What is a Cantata?

What is a Cantata? Our Principal Keyboard Steven Devine explains as he accompanies soprano Rowan Pierce in Bach's Cantata Weichet nur, betrübte Schatten (Yield now, troubling shadows) BWV202.
"A cantata is usually a short composition of several movements that features a story. The word cantata comes from the Italian 'cantare', which means 'to sing'."
