It's a small world is a well-known theme tune that can be heard at five different Disney theme parks across three different continents. The Sherman Brothers were the original artists behind the song, which they wrote along with their brother Robert Sherman and brother Richard Sherman. The purpose of the song is to foster better worldwide understanding through its use of the subject of global togetherness as its foundation.
The song is performed throughout all of the Disney parks that were just mentioned, and it has been translated into a number of different languages. Since the inauguration of the first Disney theme park, Disneyland, in Anaheim, California, in the year 1955, the song has been performed at all of the Disney parks.
