Italian overture
The
Italian overture is a piece of orchestral
music which was used to open
operas, oratorios and other large-scale works in the late 17th and early 18th century. The structure was particularly popular among Italian composers such as
Alessandro Scarlatti, hence its name.
It is a three-movement structure - the outer movement are quick, the middle movement slow. This structure was the basis of the symphony form, which developed in the early 18th century.
The Italian overture can be contrasted with the French overture, which was popular in France.
