問題解決としての音楽的思考におけるリフレクションの機能

―思考の連続性に着目して―

  This study examines the efficacy of reflection in musical thinking for problem solving.

  The research methodology adopted incorporates the use of practical methods. First, we consider the issue of reflection in the context of Dewey's theory and discuss what reflection would mean with regard to musical thinking. To this end, we planned and implemented training sessions that incorporate reflection in musical thinking to promote problem solving. This paper analyzes data from records of these sessions in the context of the relationship between reflection and continuity of thought.

  The function of reflection in musical thinking to promote problem solving was found to be as follows :

  (1) Reflection allows the subject to objectively compare the image in his mind and the actual sound and recognize the gap between the two.

  (2) It first provides the subject with clues to the cause of inconsistencies between the image and the actual sound. Then, by helping eliminate that gap, it allows the subject to make predictions to eventually narrow the gap with the image.

  (3) It helps flesh out details of the image in the subject's mind through correlations made and regeneration of the image.

  (4) Finally, it clarifies the image that the subject wants to express.
