The concerto grosso (pronounced [konˈtʃɛrto ˈɡrɔsso]; Italian for big concert(o), plural concerti grossi [konˈtʃɛrti ˈɡrɔssi]) is a form of baroque music in which the musical material is passed between a small group of soloists (the concertino) and full orchestra (the ripieno or concerto grosso). This is in contrast to the solo concerto which features a single solo instrument with the melody line, accompanied by the orchestra.
