Sinfonia

Sinfonia is an Italian term meaning "symphony" or "introduction," used in classical music to refer to a short, instrumental piece that often introduces a larger work or serves as an independent composition. Historically, it signified an orchestral piece with a structured, often lively character, typically performed at the beginning or during a work's development. In modern usage, it can also denote a standalone musical work or movement that showcases orchestral colors and thematic development, acting as a bridge or commentary within a larger composition.
