In most occasions, only the chorus, first stanza and the chorus are played or even the chorus itself. Sometimes the chorus is played twice in the beginning, and once in the rest of the anthem. In formal events (if the anthem will be played by either a military band, concert band or orchestra) the format is: Chorus (2x), First verse and Chorus (2x), with the optional introduction. If played in full the chorus is sung twice, with or without the introductiory notes.
