Are both pieces The Immortal Hour and L'incoronazione di Poppea an opera?
The Immortal Hour The Immortal Hour is an opera by English composer Rutland Boughton. Boughton adapted his own libretto from the works of Fiona MacLeod, a pseudonym of writer William Sharp.
Melodramma Melodramma (plural: "melodrammi") is a 17th-century Italian term for a text to be set as an opera, or the opera itself. In the 19th-century, it was used in a much narrower sense by English writers to discuss developments in the early Italian libretto, e.g., "Rigoletto" and "Un ballo in maschera". Characteristic are the influence of French bourgeois drama, female instead of male protagonists, and the practice of opening the action with a chorus.
