《诗经》中依体裁与音乐对诗歌所分出的类型。“风(国风)”是不同地区的音乐，大部分是民歌；“雅”是宫廷宴享或朝会时的乐歌，分为“大雅与“小雅”，大部分是贵族文人的作品；“颂”是宗庙祭祀用的舞曲歌辞，内容多是歌颂祖先的功业。“雅颂”指雅正之音，而“国风”系民间乐歌，因此“风雅颂” 既是《诗经》的体裁，同时也有高雅纯正的含义。“风雅”后来一般指典雅与高雅的事物。

In The Book of Songs, the content is divided into three categories according to style and tune: feng (ballad), ya (court hymn), and song (eulogy). Ballads are music from different regions, mostly folk songs. Court hymns, divided into daya (major hymn) and xiaoyo (minor hymn), are songs sung at court banquets or grand ceremonies. They are mostly the works by lettered noblemen. Eulogies are ritual or sacrificial dance music and songs, most of which praise the achievements of ancestors. Court hymns and eulogies are highbrow songs while ballads are lowbrow ones. Therefore, ballads, court hymns, and eulogies not only refer to the styles of The Book of Songs but also classify the songs into highbrow and lowbrow categories. Later on fengya (风雅)generally referred to anything elegant.
