Chàng cí literally combines 唱 (chàng), meaning 'to sing', and 词 (cí), meaning 'words' or 'lyrics'. Together, they refer specifically to the words that are sung in songs—distinct from spoken dialogue or written poetry. Unlike the broader term 歌词 (gēcí), which is the standard word for 'song lyrics' in pop music, 唱词 carries a stronger association with traditional Chinese performing arts, especially opera (e.g., Peking opera, Kunqu) and narrative singing forms like tanci or pingshu.

It emphasizes the textual component intended for vocal performance, often with strict metrical, rhyming, or tonal requirements suited to musical phrasing. While modern usage sometimes overlaps with 歌词, 唱词 is more formal and culturally specific—it’s rarely used for casual pop songs or karaoke. Learners should recognize it primarily in contexts involving classical or regional Chinese music theatre, where the text is inseparable from its melodic and rhythmic delivery.
