【摘要】 北魏“旋宫说”，是指《魏书·乐志》中公孙崇、陈仲儒、祖莹探讨旋宫问题的言论或观点。其原文虽语焉不详，却不乏真知灼见。经研究发现，“公孙崇说”包容了多种形态的五声音律结构，与古琴音律可以通融，具有“理论框架”的意义；“陈仲儒说”与“祖莹说”可以互为补充，二者为旋宫系统的五声音律结构提供了具有统一标准的参照物。相对《礼记·礼运》郑玄注来看，北魏旋宫诸说的形成是旋宫理论发展的一个新的里程碑。更多还原

【Abstract】 The "Xuangong" theory in the Northern Wei Dynasty encompasses the views of Gongsun Chong, Chen Zhongru, and Zu Ying on the Xuangong problem as discussed in Weishu Yuezhi. Although the original texts are not extensively detailed, they offer significant insights.Research reveals that Gongsun Chong’s theory includes various forms of pentatonic structures that align with the temperament of the Guqin, providing a "theoretical framework". Chen Zhongru’s and Zu Ying’s theories complement each other, together establishing a unified standard reference for the pentatonic structure of the Xuangong system. Compared to Zheng Xuan’s annotations in The Book of Rites·liyun, the formation of the Xuangong theories in the Northern Wei Dynasty marks a new milestone in the development of Xuangong theory.更多还原
