China on Sunday announced the release of the standard sheet music and official recording of the Chinese national anthem - "March of the Volunteers," with this year marking the 75th anniversary of the founding of the People's Republic of China and the 75th anniversary of the Chinese national anthem.

The standard sheet music for the national anthem includes orchestral, wind ensemble, and piano accompaniment scores. The official recording versions of the national anthem include orchestral version, orchestral choral version, wind ensemble version, and wind ensemble choral version, according to the State Council Information Office at a press conference on Sunday.

The released standard musical score for the national anthem has not made any changes to the melody, but focused on four areas of improvement, including standardized cover, title page, and publishing notation, unified tempo markings, as well as standardized expression terms.

The national anthem "March of the Volunteers," has lyrics by poet Tian Han and music by Nie Er. The original song greatly encouraged Chinese soldiers and civilians during the Chinese People's War of Resistance against Japanese Aggression (1931-1945). It was chosen as the national anthem in 1949.

Wu Zeng, an official from the Commission for Legislative Affairs of the National People's Congress (NPC) Standing Committee, stated at the press conference that the release of the standard sheet music and official recording of the national anthem will enhance the seriousness and standardization of its performance, broadcasting, and usage, uphold the image and dignity of the country, strengthen national consciousness and patriotism, and further promote the national spirit centered on patriotism.

China's National Anthem Law came into force in 2017 to ensure appropriate performance of the song, the Xinhua News Agency reported. 

Now, National Anthem Law, National Flag Law and National Emblem Law together constitute a relatively complete legal system of national symbols in China, Wu said.

The anthem shall be sung at formal political gatherings, including the opening and closing of National People's Congress sessions, constitutional oath ceremonies, flag raising ceremonies, major celebrations, awards ceremonies, commemorations, national memorial events, important diplomatic occasions, major sport events and other suitable occasions, according to the National Anthem Law.
