Shidaiqu
Also called shanghai popular song, era song
1920s–40s Shanghai popular song: Mandarin film and cabaret hits mixing jazz-band kit with Chinese melody (Zhou Xuan, Yao Lee). It hears Jazz for the cabaret dance-band kit and Traditional pop for the Tin Pan Alley film-song job. It already gives Cantopop that nightclub/film-song job moving to Hong Kong in Cantonese, and Mandopop the Mandarin star-ballad afterlife. Chinese opera leftover as a different lyric theatre. Chinese folk leftover as a refused catch-all.
