"Singspiel" refers to a type of light German opera that features spoken dialogue. It's known for its lightheartedness and humor, and it was popular in the 18th and 19th centuries. Bel canto, on the other hand, is a style of singing that emphasizes beauty of tone and legato (smooth, connected notes). Grand opera is a type of opera that features large-scale productions, and music drama is a term used to describe operas by the German composer Richard Wagner.
