Globalization and increased diversity within student populations generate a growing impetus toward a multicultural approach to music education in today's schools; however, student responses to world music are often initially negative (Shehan, 1985). This study investigates whether sixth-grade students become more appreciative of Indonesian Gamelan music as a result of participation in a multicultural music education program. Approximately 180 students, selected at random from an elementary school in Massachusetts, were divided into two groups. Both groups listened to an example of Indonesian music and were given a pre-test survey. The experimental group received multicultural instruction; while the control group did not. Both groups listened to the same example of Indonesian music and a post-test survey was administered. The data were analyzed to determine any changes of response. The results indicate that initially negative responses toward Indonesian music became more tolerant following multicultural music instruction. The concluding discussion addresses issues for further research and offers suggestions to improve multicultural music education in today's schools. (Contains 2 figures and 1 table.)
