Musical Beats and Dance Beats in Dunhuang Dance Scores
There is a striking instance of dual text in the Dunhuang dance score Nanxiangzi of the French collection P.3501,where two distinct handwritings repeat the same dance cues.Upon closer examination of the discrepancies,the difference lies in the description of"one beat".However,since it involves the crucial musical concept of"beat",scholars have not yet reached a consensus on its interpretation.Based on the concept of"beat type"put forward by the ancient score research team at the Sino-Japanese Music Culture Research Centre of Shanghai Conservatory of Music on the basis of P.3719 Dunhuang music scores,it can be observed that the Dunhuang dance scores contain both musical and dance beat types.A comparative analysis with the British collection's S.5643 Dunhuang dance score allows for a reinterpretation of the"erroneous transcription"in P.3501 Nangxiangzi.This highlights the independence of dance beats from musical beats in Dunhuang dance scores and their role in guiding movements.The fusion of these concepts leads to the historical disappearance of this ancient dance notation method.
