Night music; a Classical instrumental genre that combines elements of chamber music and symphonic music. The serenade is often performed in the evening or at social functions and is related to the divertimento and the cassation. A love song sung at night, performed out-of-doors for a specific individual (such as a member of a royal family). As opposed to a aubade which is played in the morning.Is often similar in form to the divertimento. Etymologically a piece for evening performance, usually outdoors, the counterpart of the morning aubade, the title came to have a much more general meaning, although it often suggests a piece of music in honor of someone or something, an extension of the traditional performance of a lover beneath the window of his mistress.
