Gilbert, who wrote the words, created fanciful topsy-turvy worlds for these operas, where each absurdity is taken to its logical conclusion—fairies rub elbows with British lords, flirting is a capital offence, gondoliers ascend to the monarchy, and pirates turn out to be noblemen who have gone wrong. Sullivan, seven years younger than Gilbert, composed the music, contributing memorable melodies that could convey both humour and pathos.
