This study aims to investigate and compare the effects of personalized vocal pedagogy against traditional standardized teaching methods on students’ technical proficiency, artistic expression, and overall learning motivation. Through an analysis of instructional approaches, teacher-student dynamics, and the role of adaptive feedback, this paper highlights how tailored vocal training enhances skill acquisition and performance confidence. While traditional group-based methods emphasize uniformity and collective progress, personalized instruction focuses on individual vocal needs, learning pace, and expressive interpretation. Findings suggest that students under personalized pedagogy demonstrate faster technical improvement and stronger emotional engagement, though challenges such as instructor workload and resource intensity persist. The study concludes with recommendations for hybrid teaching models that balance customization with scalability in vocal education.
