At this time, it was also agreed that Sansoen Phra Barami would become the anthem of the Royal Family, making Siam (and subsequently Thailand) one of the few nations on Earth to bear two official national anthems. Sansoen Phra Barami was used to herald the king, bid him farewell or otherwise pay tribute to him. In practical terms, Sansoen Phra Barami is used when the king arrives or departs from official events, and also at large sports or entertainment events. This song is also played before every movie at the cinema, for which you will be prompted to stand.
