A flag anthem is a patrioticsong or ode dedicated to a flag, usually one of a country (in which case it is also known as a national flag anthem). It is often either sung or performed during or immediately before the raising or lowering of a flag during a ceremony. Most countries use their respective national anthems or some other patriotic song for this purpose. However, some countries, particularly in South America, use a distinct flag anthem for such purposes. Not all countries have flag anthems. Some used them in the past but no longer do, such as Iran and South Africa. Flag anthems can be officially codified in law, or unofficially recognized as such through mere custom and convention. In some countries, the flag anthem may be just another song, and in others, it may be an official symbol of the state akin to a second national anthem, such as in Republic of China.
Essentially an abridged version of the Italian national anthem played with ruffles and flourishes beforehand and omitting the introductory section. The song concludes where the bridge of the national anthem would otherwise begin. Alternatively known as "Alzabandiera".
The author of the lyrics is disputed, though it is usually attributed to Tai Chi-tao. An alternate title is "Qīngtiānbáirì mǎn dì hóng", which means "The clear blue sky, white sun, and a wholly red ground". Due to political complications, this song is often played at international sporting events involving Taiwan in place of the National Anthem of the Republic of China.
