The national anthem is like a song that some countries use to represent themselves. It is played on special occasions or events, such as sports games, parades, or important ceremonies. The words of the national anthem are usually about the country's history, culture, or values.
In the United States, the national anthem is called "The Star-Spangled Banner." It was written by Francis Scott Key during the War of 1812. The song tells the story of how the American flag survived a fierce battle with the British and became a symbol of hope and freedom.
When the national anthem is played or sung, people usually stand still and pay attention. They might put their hand over their heart or salute if they are in the military. It is a way to show respect for the country and its values.
Some countries have more than one national anthem, such as Canada and Switzerland. In some places, people might sing the national anthem in a different language, depending on where they live or what their culture is.
