This study examined the effects of painting expression activities connected with music on children on the basis of the philosophy of integrated arts education that has emerged in post-modernism education. Both music and art stimulate the sensitivity of children and improve their creative thinking. Above all, children like music and art activities and they help them express their mind naturally. Therefore, art activities connected with music offers a desirable model for integrated arts education. In this study, two pieces of music with different formats but of the same theme of “spring” which is familiar to children were played to children and the children were asked to draw paintings after listening to each pieces of music. From the differences of the paintings, the correlations between listening to music and artistic expression were examined. Most children accurately read the theme of the music even though they had not received any special teaching about music, and expressed their feelings on their paintings in many different modes of expressions and different color selections. As a result, this study found that art education connected with listening to music had direct, positive effects on children. The connected education of two different areas with different domains of perception helped children cultivate capacity for synesthetic perception and express a wider width of thoughts for the same subject, suggesting the possibility of educating them as creative persons required in this diversified modern society. Therefore, art education for children through interdisciplinary learning must be continued.
