1. Drama, a form of performing arts, encompasses a wide range of presentations, including stage plays, operas, ballets, and more. These are commonly experienced in theaters, on radio, or on television.2. Opera is a specific genre within the realm of drama that combines singing, musical scores, dancing, and dramatic acting. In opera, the story is told primarily through song, often accompanied by an orchestra.3. While the English word "opera" can sometimes be used to refer to soap operas, a type of television serial, this usage is more common in certain linguistic and cultural contexts. In Chinese, for instance, terms like "肥皂劇" (soap opera) or "連續劇" (serial) are typically used to describe such television programs.4. In academic and professional contexts related to the arts, "drama" is often used as a blanket term to refer to all types of theatrical performances and related arts, a scope that is broader than that of "opera."
