Sinfonia is the Italian word for symphony, from the Latin symphonia, in turn derived from Ancient Greek συμφωνία symphōnia (agreement or concord of sound), 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 (, who gives the origin of the word as Italian). The word is also found in other Romance languages such as Spanish or Portuguese.

Sinfónía (Eng: Symphony) is the live album of 11 hits performed by one of the most recognised Icelandic pop/rock bands - Todmobile & orchestral works of the 72-piece Icelandic Symphony Orchestra (led by Bernharðs Wilkinson) at the Laugardalshöll in Reykjavík on November 14, 2003. The album/concert also featured the return of the original lead singer, Eyþór Arnalds. There was a corresponding DVD release with this album.
