The purpose of this paper is to develop the logic of unit construction in school music education based on the concept of the generating of music and the theory of reconstruction of experience by J. Dewey. The concept of the generating of music is based on Dewey's theory of reconstruction of experience, which is considered as the purpose of education. The method for reconstruction of experience is "inquiry". The process of inquiry is the transformation from an uncertain situation to a certain situation. This transformation is accomplished by the cycle of "immediate experience-reflective experience-new immediate experience". This cycle works in every unit of thinking and can be conceptualized as the process of learning. The aesthetic inquiry, including musical inquiry, has the same structure as general inquiry even though musical inquiry has its own characteristics due to its unique material. Therefore, the cycle can be applied to both music inquiry and music learning process. By using the cycle as the framework of unit construction in school music learning, three elements for unit construction have been found: experience of inquiry, reflection of inquiry, and evaluation of inquiry. From this logic, "immediate experience-reflective experience-new immediate experience" is presented as a model of unit construction based on the concept of the generating of music.
