This article mainly focuses on the reform of vocal performance teaching under the guidance of core competencies

and explores the construction of a dynamic teaching content library to address the problem of monotonous and rigid teaching content. It is of great practical significance for promoting the deep integration of skill training and cultural immersion and creative practice

as well as facilitating the cultivation of core competencies such as aesthetic perception. The paper first clarifies the core principles for constructing the content library

and then divides it into three interrelated sections of basic core

cultural expansion

and creative practice. Each section has its specific focuses and progresses hierarchically. According to the study

the basic core section consolidates the foundation skills of singing

the cultural expansion section explores diverse cultural resources and achieves interdisciplinary integration

and the creative practice section provides open-ended materials for composition and improvisation. The collaborative efforts of these three sections enables the teaching content to serve as a high-quality carrier for cultivating competencies

effectively solves the mismatch between teaching content and the needs of competency cultivation

and provides a feasible approach for the innovation of vocal music teaching content.
