Abstract :In Okinawa, there is an original stringed instrument which is called "Sanshin". These musical instruments are played with unique score book called "Kunkunsi". In this paper, we proposed how to transcript the sound of playing Sanshin to the musical note. As preprocessing we attempt pitch distinction of Sanshin sound. To distinct the pitch we tried to delete the overtone spectrum. In addition, we derive the attacking time of Sanshin sound by sharpness of go up of waveform. The distinction with this method was done from an actual consecutive Sanshin sound, and good results were obtained on the single sound.
