Zu Xiaosun (Chinese: 祖孝孙) was a Chinese musician of the Sui and Tang dynasties. During the Kaihuang reign period (581 - 600) of Emperor Wen of Sui he was appointed as Xielülang (协律郎), joined the melodizing of ritual music, and received orders to learn the Jing Fang Temperament (京房律法) from Mao Shuang (毛爽). After the founding of Tang Dynasty, Zu served as zhuzuolang (著作郎), libulang (吏部郎) and taichang shaoqing (太常少卿).
From 626 to 628, Zu composed music for Emperor Gaozu of Tang. Zu cooperated with Zhang Wenshou (张文收), solved the problem of tuning (调律) and change of keys of twelve temperament (十二律旋宫).
All Zu's works about music temperament had already been lost, only some summaries of his theory were recorded by Annals of Music (《音乐志》) and Annals of Rites and Nusic (《礼乐志》).
Its seemes so fucking stupid to me, that this "state of freedom" can claim a year of someones life. It seems irrelevent what he feels or what he needs, put on your uniform and leave your brains behind. Cheap labour for the state, no opinions you must stay to serve someone that you hate and do exactly what the say. Ill comunication builds the ground its undispiteble. And as the free wills pulls att opposite directions, they infringe a law with anotheone and they ask themselves why there credibility has gone. Ciemency and reaproval respect. how good is a soldier with the sesitivity intact, all fucking armys puts the act before the thought.in a way it aint their fault, the are just doing what there thaught. I do question their intent to defend the king and crown a piece of cloth we represent and for that its not worth to go down .......NOT LIKELY!!!!!
