丁若镛活跃于18、19世纪的李氏朝鲜后期,是朝鲜实学思想的集大成者,在经学、哲学、政治学、经济学、音乐等方面都有很深的造诣。其中,他的音乐成就主要集中于其音乐著作《乐书孤存》之中,此书也是了解丁若镛实学思维支配下音乐思想的点睛之作。本文试从文献学的角度就《乐书孤存》进行初探,寻找此书的编纂特征以及它与中国典籍所记载的音乐理论的关系,进而来剖析中国古代的音乐理论对于古代朝鲜半岛的影响。初次探究,期望得到学者们对于丁若镛及其音乐思想的关注。 The late Joseon Dynasty, active in the 18th and 19th centuries, was the master of North Korea’s real-learning thinking and had deep attainments in economics, philosophy, politics, economics and music. Among them, his musical achievements are mainly concentrated in his music book “Solitary Music Book”, this book is also a comprehension of Ding Ruo-pang real thinking under the control of the music ideas at the finishing touch. This article attempts to probe into the issue of “soliloquy of musical instruments” from the angle of philology and find out the compiling features of this book and the relationship between it and the musical theory recorded in Chinese classics, and then to analyze the influence of ancient Chinese musical theory on the ancient Korean Peninsula . For the first time, I hope to get the scholars’ attention to Ding Ruo-juan and his music thoughts.
