I want to know the answer to the following question:
What type of familiar translation may be seen during an opera?
All the background I'm provided with is that "Translations of sung texts—whether of the above type meant to be sung or of a more or less literal type meant to be read—are also used as aids to audiences, singers and conductors, when a work is being sung in a language not known to them.". Is that enough to answer the question?
