Answer
The Elements is a song from the musical "Schoolhouse Rock!" that parodies the "Major-General's Song" from Gilbert and Sullivan's "The Pirates of Penzance." Both songs feature a rapid-fire recitation of a long list of items, with the "Major-General's Song" listing military ranks and the "Elements" listing the chemical elements. The parody humorously adapts the original song's structure and rhythm to a scientific context, making it both educational and entertaining.
