Finale concertato

A finale concertato is any finale of an opera's penultimate acts which features several main characters singing simultaneously but independently, often expressing different emotions or perspectives.
Quoting Denise Gallo, “by the late eighteenth century, the finale concertato was gaining popularity; by the following century, it had become standard fare.” According to Scott F. Balthazar, “y the 1830s, it had a clear and relatively conventional form.” Finali concertati may be found in the operas of such composers as Gioachino Rossini and Giuseppe Verdi.
