A sinfonietta is a symphony that is smaller in scale or lighter in approach than a standard symphony. Although of Italian form, the word is not genuine in that language and has seldom been used by Italian composers. It appears to have been coined in 1874 by Joachim Raff for his Op. 188, but became common usage only in the early 20th century (Temperley 2001).
