culture
Du Fu (杜甫) wrote 《曲江二首》 (Two Poems at Qujiang) here in 758. Its line 人生七十古来稀, 'a life of seventy has been rare since ancient times', gave Chinese 古稀 as a word for the age of seventy.
usage
曲 is qū 'winding' here, after the curving water of the lake, not qǔ 'song'. The lake, 曲江池, lies in Xi'an's 曲江新区, around the Giant Wild Goose Pagoda (大雁塔).
