Translator’s Note: Xilutang Qintong is one of the most comprehensive and ambitious project and achievement in premodern qin music publication history. Containing 170 pieces including 19 with lyrics, it is by far the largest single manuscript collection of existant qin music to date. Tianwenge Qinpu in 1876 comes in second, with 145 melodies.
What makes this book especially precious, asides from the surviving original being a handcopied version stored by Li Yunzhong of Tianjin with Folio 5 (including fingering index and L/R hand explanations) now lost, is the 75 unique or sole surviving versions of melodies not found in any other manuscript. Of the 29 modal themes in 14 different tunings, half of the tunings are unique to the melodies in this book. In summary, there is no overstatement to the musicological and historical importance of this collection, which the author has spent the majority of his life scouring the Ming landscape in search and editing for this compendium.
