(July 2011) (Learn how and when to remove this template message) </Td> </Tr> <P> A concerto (/ kənˈtʃɛərtoʊ /; plural concertos, anglicised from the Italian concerti, which is also used in English) 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 ." However, in recent centuries and 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 . </P> <P> The word concerto comes from Italian; its etymology is uncertain, but it seems to originate from the conjunction of 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 between episodes of opposition, cooperation, and independence to create a sense of flow . </P>
