The anthem for a person, office or rank is music played on formal or ceremonial occasions in the presence of the person, office-holder, or rank-holder, especially by a military band. The head of state in many countries is honored with a prescribed piece of music; in some countries the national anthem serves this purpose, while others have a separate royal, presidential, or, historically, imperial anthem. Other officials may also have anthems, such as the vice-regal salute in several Commonwealth realms for the Governor-General, Governor, or Lieutenant Governor. Ruffles and flourishes may be played instead of, or preceding, such an anthem.
