Wikipedia:WikiProject Opera/Start-class criteria

The article has a usable amount of good content, but it is weak in many areas, usually in referencing. Quality of the prose may be distinctly unencyclopedic, and MoS compliance non-existent; but the article should satisfy fundamental content policies such as notability and BLP, and provide enough sources to establish verifiability. No Start-Class article should be in any danger of being speedily deleted.

Start-Class articles on operas must contain a table of roles with associated voice types (though not necessarily with names of original performers) and a basic plot synopsis that is a minimum of a paragraph in length. The article must provide the date and place of the opera's composition/premiere, the name of the composer/librettist, the opera's genre, and a basic discussion of the opera's structure. The article should provide some contextual information in the following areas (although certain sections may be missing entirely and other sections bairly touched on): Background/history of composition, performance history after the premiere, musical/textual analysis, critical appreciation, and recordings. The article should be referenced to at least one reliable source but may lack in-line citations or appropriate notes. The article should be placed in appropriate categories and may lack illustrations, notable arias, and external links.
