1660s, from serenade (n.). Related: Serenaded; serenading.
originally, a nocturnal song of courtship, and later, beginning in the late 18th century, a short suite of instrumental pieces, similar to the divertimento, cassation, and notturno. An example of the first type in art music is the serenade "Deh! vieni alla finestra" ("Oh, Come to the Window"), from Wolfgang Amadeus Mozart's Don Giovanni. The instrumental serenade gradually lost its association with courtship and became (about 1770) primarily a collection of light pieces such as dances and marches suitable for open-air, evening performance
