Sinfonia

Sinfonia is the Italian word for symphony, from the Latin symphonia, in turn derived from Ancient Greek συμφωνία symphōnia, from the prefix σύν (together) and ϕωνή (sound). In English it most commonly refers to a 17th- or 18th-century orchestral piece used as an introduction, interlude, or postlude to an opera, oratorio, cantata, or suite. The word is also found in other Romance languages such as Spanish or Portuguese.
