Beethoven String Quartets -> "The second movement of the first one was thought to have been inspired by the tomb scene from Romeo and Juliet. A section of the Cavatina movement of the 13th one is marked Beklemnt, and the finale of the seventh is based on a Russian folk theme. The finale of the last one is marked with an epigraph that reads "The difficult resolution," while the Molto Adagio of the 15th one is a song of thanksgiving in the Lydian mode. The original finale of the 13th is now known as the Grosse Fugue. FTP, name this group of sixteen works, with subtitles such as "Serioso," "the Harp" and "Razumovsky." "
Anthem chorus -> "The first chorus of Messiah, And the Glory of the Lord, also has lyrics taken from Isaiah 40. It is an example of this kind of chorus in which each specific line of text is represented by a particular line of music."
Latin dance and Smooth dance -> Categories of ballroom dancing used in international competitions. It's possible that these categories are separate, as I've seen them both grouped together as well as named the "two major types of ballroom dancing".
