1. Bel canto: 19th century Italian opera term; the actual definition of
this style is ambiguous and is most often modernly associated
nostalgically for a style or tradition of singing that has been lost.
2. Grand Opera: Italian opera in 4-5 acts, large scale casts and
orchestra, lavish sets and design, and plots based on dramatic historic
events.
3. Verismo: Italian opera that depicts realistic (and sometimes
violent) events of everyday life; tends to focus specifically on the
lives of the lower class.
4. tragedie en musique: a form of French opera; distinguishing features are dance music and choral writing.
5. opera comique: "comic opera"; a French genre of opera in
which arias are alternated with spoken dialogue; common tunes were woven
into the opera but given different words.
Hope this helped :D
