In the wave of new educational curriculum reform, exploring how to stimulate and cultivate college students' musical creativity has become an important topic that cannot be ignored. In order to achieve this goal, we must focus on enhancing the innovative ability and consciousness of college students, which is the key to cultivate their musical creativity. This study takes the students in the music clubs of colleges and universities in Zhejiang as the object, and discusses the influencing factors of the creativity of music creation from the perspective of teachers. Through the establishment and analysis of the structural model, it is found that teachers' intelligence, personality, motivation, knowledge and skills, diversity of music preferences, social and cultural tendencies and other factors have significant effects on students' musical creativity. Among them, long-term memory and retrieval ability, openness to experience, internal motivation, diversity of music preferences and sociocultural tendency have positive effects on music creativity. Based on the research results, this paper puts forward specific educational countermeasures and suggestions, aiming to stimulate students' musical creativity comprehensively and improve the quality of music education through innovative teaching methods, changing the role of teachers, weakening the sense of competition in learning, integrating collective culture and other measures. This study not only enriches the theoretical system of musical creativity, but also points out the direction of college music community education practice, and provides valuable inspiration and practical reference
