If early and High Tang are regarded as 'Spring" and "summer", Middle
Tang is "fall", or the season of harvest. An Lushan's revolt in 755
produced disastrous consequences in Tang, and it never fully recovered.
Poetry, therefore, is more "autumnal" in air, as to keep up with changed
nature. There came a new collection of poetry from a new string of
poets, varying in style and ranging in subject matter.
Wei Yingwu (737-789) followed the pastoral style of Wang Wei, as
seen in "On the West Stream at Chuzhou". Li Yi (748-827) followed
the style of frontier poems, for example, in "On Hearing a Flute at
Night Atop a Victor's Wall". Both poets lacked the exuberant tone
that was more common in earlier years.
The most important Middle Tang poet is the famous and prolific Bai
Juyi (773-846), who mingled Du Fu's realism with Li Bai's romanticism.
He was also an innovator, writing "new Music Bureau Ballads" with
deliberate simplicity. Bai placed high value on social criticism,
as well as writing about Buddhist influence on poets.
Buddhist influence revolted Confucian innovator Han Yu (768-824),
who submitted to the emperor a memorial that reprimanded His Majesty
for his devotion to Buddhism. Consequently, Han was exiled 8000 miles
away.
Lie Yuxi (772-842) composed Bamboo Branch Songs and Willow
Branch Songs- the early forms of tuned poetry. Tuned lyrics marked
by lines of varying length came to performance in Middle Tang.
