"God Save the Queen" (alternatively "God Save the King") is the national and/or royal anthem in a number of Commonwealth realms, their territories, and the British Crown Dependencies. The words and title are adapted to the gender of the current monarch, i.e. replacing Queen with King and she with he when a king reigns. The author of the tune is unknown and it may originate in plainchant, but a 1619 attribution to John Bull is sometimes made.
