What is "canzonetta"

n. A style of popular Italian secular vocal composition which originated around 1560, or a piece composed in this style

In music, a canzonetta (; pl. canzonette, canzonetti or canzonettas) is a popular Italian secular vocal composition that originated around 1560. Earlier versions were somewhat like a madrigal but lighter in style—but by the 18th century, especially as it moved outside of Italy, the term came to mean a song for voice and accompaniment, usually in a light secular style.
