ouverture

An overture is a musical composition, typically an orchestral introduction to a larger dramatic work like an opera. It can also be a standalone instrumental piece. Early operas featured short instrumental pieces or sung prologues. The French overture, popularized by Jean-Baptiste Lully, typically began with a slow section in dotted rhythms, followed by a fast, fugal section, and often concluded with a slow dance. The Italian overture, common in the late 17th and 18th centuries, featured three movements: fast-slow-fast, and influenced the development of the symphony. Composers like Christoph Gluck and Richard Wagner used overtures to set the mood and foreshadow the drama of the accompanying opera. The concert overture emerged as an independent orchestral work, often in sonata or free form, intended for concert performance.123
