National Music Day (Hari Musik Nasional) is observed in Indonesia every March 9 to commemorate the birthday of Wage Rudolf Soepratman, the composer of the national anthem "Indonesia Raya." Established in 2013, the holiday aims to honor Supratman's legacy and promote appreciation for Indonesian music. The day features various events, including concerts, music conferences, and awards ceremonies, celebrating renowned Indonesian composers and musicians. Indonesia's music scene is notably diverse, influenced by its multi-ethnic society and foreign music styles, with traditional genres employing percussion instruments like gongs and drums. The idea to designate this day was proposed by the Indonesian Association of Singers, Songwriters and Musicians (PAPPRI) in 2003, reflecting the country's rich musical heritage.
