This study explores the potential of the MVP (Musical Pitch Visualization Perception) support system integrated with Google Glass, designed to enhance wind instrumentalists’ performance. The system aims to improve intonation accuracy, reduce cognitive load, and provide flexibility in visual and physical orientation during performance. While previous research has primarily relied on subjective evaluations and qualitative methods, this study employs OpenPose for motion capture to obtain objective data on performers’ body movements. An experiment was conducted where a saxophonist played a B-flat major scale while keeping pace with a metronome, using both a conventional tuner and the MVP system. The results indicated that the MVP system enabled more fluid and detailed body movements, suggesting an increase in the performer’s freedom of movement and more precise acquisition of metronome information. Despite the promising findings, the study acknowledges limitations due to the small sample size and recommends further research with more participants and dedicated motion capture equipment for more robust analysis.
