 note = {The Bhutanese folk song "Dranyen Lamdren" is performed by a stringed instrument called the Dramyin (sgrasnyan). We studied microtones produced by the "Dranyen Lamdren" during a performance of the Bhutanese musicians Daw Penjor, and Jigme Drukpa, who also studied abroad in Norway, and Ryukyu court music known as "Shuri-bushi". As a result, a perfect fourth pitch interval is played with a pitch that is almost the same as equal temperament, but a third and seventh pitch interval are played with a microtone pitch interval located between the major and minor pitch. In addition, in the Ryukyu scale, it was observed that two sets of tetrachords were used independently. In the Bhutanese scale, unlike the Ryukyu scale, it was observed that there were few elements of leading-tones in the fifth note.},
