Analysis of Thai Tuning System by Mathematical Formula

บทคัดย่อ

          This study focuses on the traditional Thai tuning system. Tunings of Thai classical music has been a source of disagreement. Focusing on Ranat Ek, by measuring the vibration frequency of each sound, we can analyze the sound cents of intervals, and calculate whether intervals are consonant through the existing mathematical formula. By comparing the vibration data of Ranat Ek on various school instruments, the data are analyzed, and mathematical formulas are used to calculate whether the Thai tuning system consonance or not. Research objectives were (1) to measure the tuning systems of each school to get reliable data. (2) To study the formula of western tuning system that used to measure Thai tuning system, and a tuning system is recommended as the standard of Thai tuning system. This study was qualitative research which collected data by interview 8 experts.
          The result was although schools have different tuning systems, more and more schools are choosing the government's tuning system as the standard. The author boldly predicts that this is the future development trend of Thai tuning systems.
