There are several reasons why having supertitles for English and English-translated operas is beneficial. First, the style of most operatic singing makes it difficult to deliver the language in an easily understandable way. Second, many words in operettas and translated English operas are archaic or unusual. The Rake’s Progress is an excellent example of an English opera that benefits having supertitles for its audience. Finally, this is an excellent opportunity to include hearing-impaired patrons and can result in a positive community outreach opportunity.
Please be aware that if the work needing titles is not in the public domain, it will be treated somewhat differently. Please see this faq for more information.
