 The sovereign and her or his spouse are saluted with the entire composition, while other members of the royal family who are entitled to royal salute (such as the Prince of Wales, Duke of Cambridge and Duke of Sussex along with their spouses) receive just the first six bars.The first six bars also form all or part of the Vice Regal Salute in some Commonwealth realms other than the UK (e.g., in Canada, governors general and lieutenant governors at official events are saluted with the first six bars of "God Save the Queen" followed by the first four and last four bars of "O Canada"), as well as the salute given to governors of British overseas territories.In "The Oxford Companion to Music", Percy Scholes points out the similarities to an early plainsong melody, although the rhythm is very distinctly that of a galliard, and he gives examples of several such dance tunes that bear a striking resemblance to "God Save the King/Queen".
