Operatic pop or popera is a subgenre of pop music that is performed in an operatic singing style or a song, theme or motif from classical music stylized as pop.
 According to music historians, operatic pop songs became most prevalent with the rise of Tin Pan Alley musicians during the early 1900s.
 One influence was the large influx of Italian immigrants to the United States who popularized singers such as Enrico Caruso and inspired the creation of "novelty songs" using Italian dialect.
 The songs often used operatic repertory "to make a satirical or topical point".
 Popularized by American Vaudeville, musical comedies, jazz and operettas, examples include Irving Berlin's "That Opera Rag", Billy Murray's "My Cousin Caruso" and Louis Armstrong's riffs on "Rigoletto" and "Pagliacci".
 The subgenre subsequently dwindled after the 1920s but revived during the rock music era with albums such as The Who's "Tommy" and Queen's "A Night at The Opera".
