- Mozart. Standard opera repertoire begins with Mozart and includes 5 operas with no opera seria. I might add any Gluck reform operas here.
- Bel canto. The next big group is Italian bel canto by Rossini, Bellini and Donizetti and includes 6 operas.
- Verdi. He could be lumped with bel canto but is too significant for that. By himself he counts 10 operas which is more than the other three composers combined.
- Wagner. With 8 standard repertoire operas, he makes a group by himself. Humperdinck with his only one opera I would lump with Wagner, since he is Wagner's only true disciple.
- Romantic not Verdi or Wagner. We have 10 operas in this category, including operas by Gounod (1), Bizet (1), Dvorak (1), Offenbach (1), Johann Strauss (1), Tchaikovsky (2) and other composers, including Berlioz and some operetta composers. Anyone who composes in the romantic style could be included here.
- Verismo. This is a list of 7 operas, 5 of them by Puccini. All of Puccini is included here whether or not the opera is truly verismo (deals with stories from the lower classes). I am aware of the fuzzy use of terminology, and it is not done from ignorance. For me this is a musical style that adopts features of Wagner into the larger Italian style, including making the opera through composed. Cilea, Giordano, Mascagni, etc. Sometimes I just call this the BEST PUCCINI AWARD.
- Strauss, R. This is only 3 operas. If I have seen a few operas by Richard Strauss, I include him as a separate group. Otherwise he groups with the Romantic not Verdi or Wagner.
- Baroque. This consists mostly of operas by Handel but extends all the way back to Monteverdi, the first significant opera composer. Italian musicology is very active now and may produce some performable operas from this period.
- Modern. Styles include Impressionism (mostly just one opera), Expressionism (mostly just two operas), Modernism (A lot of operas, none of them popular), Minimalism (Glass, Adams), English (mostly Britten), Janáček, etc. Jazz operas appear occasionally. People still compose atonal music. There are never enough examples of any given style to compare a group of operas, so I stick with this large category.
These are not standard musical style periods, but are the broad categories into which opera repertoire falls. The point is to try to make a basis for comparison. If you look back, you will see that they are constantly in flux. The KK Awards began in 2012.
