《太平广记·卷二百零四·乐二》
唐懿宗一次召见乐工。乐工方始为懿宗演奏《道调弄》，于是懿宗用手打着拍子，因此乐工就随着懿宗拍节演奏曲子，命名曲子为《道调子》。
懿宗一日召乐工，上方奏乐为《道调弄》，上遂拍之。故乐工依其节，奏曲子，名《道调子》。
Tang Yizong once summoned musicians. The musicians began to play the song "Daodiao Nong" for Yizong, so Yizong clapped his hands along to the beat, so the musicians played the song along to Yizong's beat and named the song "Daodiaozi".
