A serenade is commonly of a multi-movement structure, ranging anywhere from four to up to ten movements. They usually are constructed with a fast opening movement, followed by middle slow movements that alternate with fast ones and close with a fast presto or allegro movement. There are strong influences from chamber music, and serenades can be subtly inserted into a chamber music program. A serenade can be considered somewhere in between a suite and a symphony, but is usually of a light and romantic nature—casual and without too many overly dramatic moments.[4]
