Influence of Stage Performance Psychology on Piano Playing and Adjustment Strategies

Piano playing is not only a combination of technology and art but also a complex psychological process. However, in stage performances, many performers are affected by nervousness, which affects the quality of their performance, manifesting as distraction, stiff fingers, and uncontrolled rhythm, resulting in a decline in musical expression. To this end, this paper studies the impact of stage performance psychology on piano playing and explores effective psychological adjustment strategies to improve performers' ability to control details. By analyzing the performance of performers in different psychological states, this paper explores the psychological adjustment strategies in the performance preparation stage, including the coping methods of personalized tension and anxiety and situational tension and anxiety. At the same time, the synergy of vision, hearing, touch and movement is studied to optimize the performers' instant memory ability and sense of rhythm. In addition, combining psychological theory with performance practice, strategies such as improving concentration, simulated stage rehearsal, relaxation training and positive psychological suggestion are proposed to reduce psychological pressure and enhance stage adaptability. The study shows that after psychological adjustment training, the error rate of the experimental group drops significantly to 3.2% ± 0.6, a decrease of about 39.6%, indicating that psychological adjustment strategies (such as relaxation training, concentration training, simulated stage rehearsal, etc.) have obvious effects in improving performance accuracy.
