Question: Are Il re pastore and Giasone both operas?
Sentence (from "Calliroe"): The opera follows the usual pattern of "opera seria" of the time: "secco" recitative interlaced with "da capo" arias. Within this format Sacchini introduced strong dramatic music to suit the libretto: "stromentato" recitative is also used for extra dramatic effect, and the arias are sometimes interrupted by bursts of recitative.
Relevant evidence: No
