This episode discusses the differences in tonal patterns between wujue and qijue, which had a clear impact on poetic practice. After the Tang, wujue became increasingly rare; we can conclude that poets no longer saw creative potential in the form—the great Tang writers had exhausted it. Qijue, on the contrary, remained one of the most popular and expressive poetic forms throughout the classical period.
