With the rapid development of information technology, the construction and sharing mechanism of the teaching resource base has become an important means of informatization of vocal music education. The article proposes the construction and sharing of a personalized teaching resource system based on a collaborative filtering recommendation algorithm, constructs a personalized recommendation module through the study of collaborative filtering, and further improves the personalized recommendation algorithm. Then, it elaborates on the relevant contents of user interest modeling, records and manages the user's interest, describes the user's potential interest needs, records the user's behavior by building a model, and finally analyzes the application of the teaching resource library. When the boundary value of request concurrency does not exceed 1000, the response time of the teaching resource library page is no more than 2.5 seconds. When the teaching resource library is used to process a file of 100MB size, the upload speed of the WebSocket method is 153s faster than FancyUpload. More than 70% of the students think that the use of the teaching resource library in the vocal music class can greatly enhance the effect of vocal music learning.
