Опера серія is a genre of opera that emerged in the late 17th century, characterized by its serious themes and often tragic narratives. It typically features noble characters and explores profound emotional and moral dilemmas. The music is usually structured with arias, recitatives, and orchestral interludes, emphasizing vocal virtuosity. This style of opera was popular in Italy and influenced many composers, including Handel and Mozart. Опера серія often contrasts with оперу коміка, which focuses on lighter, comedic subjects. The genre played a significant role in the development of Western classical music and opera as a whole.
