National anthems

“Glory to Hong Kong,” a rousing orchestral piece created by protesters, has been sung in chorus in malls, and played on the streets on the harmonica, sending Beijing a clear message. Hong Kong-based writer Vivienne Chow wrote last year: “When people identify with a song, you don’t need a law to make them sing and love it.”

“Music is a tool for unity,” the composer of “Glory to Hong Kong,” who wants to be known only as Thomas, told Time. “I really felt like we needed a song to unite us and boost our morale.”
