To establish a foundation for people to remain involved in musical culture throughout their lives, we sought to find new directions for music lessons at school, referring to the results of a field survey of the Bhutanese tsangmo singing dialogue. In this study, we focused on the present state of tsangmo in radio broadcasting and school events. After referring to Bhutanese singing culture, we applied its dialogue style in music lessons for the lower grades in primary schools. By sharing the meaning and using familiar forms of the song text and melody, children were able to communicate with each other and showed the capacity to develop new learning processes in the playful singing dialogues. This approach may offer us a key to reconsidering the free expression of one's feelings through singing.
