Concerto

A concerto (pronunciation: /kɒnˈtʃɛərtoʊ/ from the Italian: concerto, plural concerti or, often, the anglicised form concertos) is a musical composition, whose characteristics have changed over time. In the 17th century, "sacred works for voices and orchestra were typically called concertos."J. S. Bach "was thus reflecting a long-standing tradition when he used the title 'concerto' for many of the works that we know as cantatas.". But in recent centuries, up to the present, a concerto is a piece usually composed in three parts or movements, in which (usually) one solo instrument (for instance, a piano, violin, cello or flute) is accompanied by an orchestra or concert band.

The etymology is uncertain, but the word seems to have originated from the conjunction of the two Latin words conserere (meaning to tie, to join, to weave) and certamen (competition, fight): the idea is that the two parts in a concerto, the soloist and the orchestra or concert band, alternate episodes of opposition, cooperation, and independence in the creation of the music flow.

The concerto, as understood in this modern way, arose in the Baroque period side by side with the concerto grosso, which contrasted a small group of instruments called a concertino with the rest of the orchestra, called the ripieno. The popularity of the concerto grosso form declined after the Baroque period, and the genre was not revived until the 20th century. The solo concerto, however, has remained a vital musical force from its inception to this day.
