This treatise`s main point is to investigate the strategies of the developmental teaching and learning which are valid in the Danso-class of elementary school. Danso has been appointed as a musical instrument to be played in the class of elementary school since the fifth process of the educational course. Although 20 years has passed since then, however, this course is still considered very difficult to follow by most of the students and teachers who should be educated at least more than two times. It is my understanding, therefore, that we should try to develop various ways of solutions that can resolve many problems in Danso course of elementary school by providing the ``universal`` orientation for teachers. The point that we pay attention to in this treatise is that I apply the tonic solfa according to the movable-do system of Kodaly partially in order to improve the unsatisfactory circumstances of the Danso class of elementary school. His method provides us with very efficient means in learning syllable names and reading musical notes in Korean traditional music. In this study, we will see the strategies of the developmental teaching and learning in the Danso-class of elementary school according to the six levels.
