<p>This study examines the impact of wearable technologies on posture and movement accuracy in pianists during the learning process. The primary objective was to determine how the use of the Upright Go biofeedback device influences physical parameters and the effectiveness of exercise performance. To achieve this goal, a comparative study was conducted, in which participants were divided into two groups. Participants in Group A utilized the Upright Go device for posture monitoring and correction, whereas Group B followed a traditional training methodology. The study involved students from the Shenyang Conservatory of music, with 30 participants in each group. Prior to using the device, an individual posture calibration session was conducted for Group A. Over a 4-week period, both groups practiced for 1 h daily, performing identical musical exercises. At the end of the course, participants completed a test assignment designed to assess changes in posture and movement accuracy. To analyze the results, quantitative methods, including Student’s t-test and ANCOVA, were employed, alongside qualitative methods such as semi-structured interviews and thematic analysis. The findings indicated that participants in Group A demonstrated a significant improvement in spinal deviation angle (an average of 6.4° compared to 13.7° in Group B), as well as greater accuracy and fluidity of movements. Additionally, participants using the device reported a reduction in physical tension and discomfort during practice sessions. Statistical analysis confirmed the significant influence of wearable technologies on key aspects of piano learning. This study highlights the potential for integrating wearable devices into educational processes aimed at enhancing students’ awareness of proper posture and developing precise movement coordination skills. The findings may contribute to the development of innovative methodologies in music education and the improvement of musicians’ physical training.</p>
