The unbalanced characteristics of the current music education information resources are becoming more and more obvious. This paper builds a resource-sharing model framework with the help of cloud computing technology and designs five major mechanisms for resource sharing in music education. Afterward, the value of educational resources is weighted and calculated, and the incentive mechanism for music education resource points is formulated. Finally, the sharing and value of music education resources are investigated, and the feasibility of the mechanism is verified. Under the point incentive mechanism in this paper, fragmented resources have the lowest economic benefit exchange value, followed by complete resources, while curriculum resources have the highest exchange value, and the exchange value scores of the three resources are 0.069-0.146, 0.345-0.645, and 0.580- 1.0 respectively. Additionally, when the number of resources shared is greater than 5, the benefits of shared resources become more stable. This is related to the fact that participants will adjust the amount of their contribution in the sharing system according to the contribution of other participants. A large number of shared resources with low value will result in a relatively large waste of resources. Not only can they not fully contribute their resources, but they also cannot fully enjoy the resources contributed by other people. Therefore, the value of the subject itself will have an impact on the benefits of the shared resources.
