演唱 (yǎn chàng) is a verb meaning 'to perform (a song)'—specifically, to sing live in front of an audience, often with expressive delivery and stage presence. The character 演 (yǎn) means 'to perform' or 'to act', carrying connotations of presentation and interpretation; 唱 (chàng) means 'to sing'. Together, they emphasize the artistic, public aspect of singing—not just vocalizing, but performing musically and expressively.

This word is commonly used for formal or semi-formal musical performances: concerts, competitions, school recitals, or televised talent shows. It’s more specific and elevated than simply 唱 (chàng) or 唱歌 (chàng gē), which refer to singing in general (even casually). 演唱 implies intentionality, preparation, and audience engagement, and it rarely appears in passive or private contexts like singing alone at home.
