Abstract :We analyzed sound waves of Ryukyu's Sanshin by the micro-computer with the interface of A/D- converter. We got the musical interval ratio of Hon-cho-si of Ryukyu's Sanshin. It is very similar to that of the just temperament scale. We got about 740 Hz as the lowest resonance frequency of the trunk of Ryukyu' s Sanshin. According to the results by main component analysis, the contribution value of the first main component is not so large as we expected. It means the tone of the Sanshin has a wide variety.
