Under the wave of digital intelligence technology, vocal music education has ushered in a new opportunity for reform. There are some disadvantages in traditional vocal music teaching, such as “separation between theory and practice” and “fragmentation of knowledge system”, which need to be solved urgently through model innovation. This paper focuses on the reconstruction of teaching mode driven by digital intelligence technology, and puts forward a “three-wheel cycle” progressive vocal music course model. This model relies on the deep integration of online resource platform and offline training space, and builds a knowledge closed loop of “self-learning before class-intelligent interaction in class-accurate feedback after class” with the help of tools such as “vocalist” intelligent practice APP and learning pass. Through the first round of consolidating basic theory and core skills, the second round of deepening theoretical expansion and skill strengthening, and the third round of promoting project-based practice and independent inquiry, the problem of insufficient knowledge systematization of vocal music courses is systematically solved, and the traditional tendency of “emphasizing skills over theory” is promoted to provide a practical example for the digital and intelligent transformation of vocal music education.
