The author contends that the first Thai textbook on musicology was the one written by Phra Aphaiphonrop (Phloi Phenkun). It is not the books authored by Montri Tramot or Phra Chenduriyang, as many believed. The brief biography of Phra Aphaiphonrop was presented. Meanwhile, in the latter part of the article, the author presents the summary of the textbook's content, mainly focusing on music theory.
