Concertino typically refers to a small concerto, typically featuring a solo instrument accompanied by an orchestra. However, there are several synonyms that can describe this type of musical composition. One such synonym is "concertante," which refers to music performed by a soloist or small group of instruments and accompanied by an orchestra. Another synonym is "sinfonia," which is a musical work divided into several movements and typically composed for a smaller orchestra. Finally, "serenade" is sometimes used as a synonym for concertino, particularly when the composition is lighter and more romantic in tone. Regardless of the synonym used, the concertino remains a popular and important form of classical music.
