The term LEONCAVALLO OPERA refers to two operas composed by Ruggero Leoncavallo, an Italian opera composer. The first is PAGLIACCI (9 letters), which is a two-act opera that premiered in 1892 and tells the story of a commedia dell'arte troupe in Calabria, Italy. The second is I PAGLIACCI (10 letters), which is a one-act opera that premiered in 1892 and is a prequel to PAGLIACCI. Both operas are considered to be some of the most important works of the verismo style of opera.
