The Baroque period saw the development of opera, which originated from ancient Greek tragedies. Operas featured an overture, orchestra, chorus, solo parts like arias, and elaborate stage productions. Several styles of opera developed in different regions of Europe. Instrumental music also grew in importance, featuring new genres and forms like the fugue, variation, and dance suite. Notable Baroque composers included Bach, Handel, Monteverdi, Corelli, Purcell, Rameau, and Vivaldi.
