| Rachmaninoff’s Piano Concerto No.2 in C minor is a world-renowned masterpiece created by Rachmaninoff after experiencing a low point in his life and continuously cooperating with psychotherapy.It has a strong artistic appeal.This paper selects the live performance versions of the two performers,and tries to analyze the two performance versions from the perspective of performance psychology,after a preliminary text analysis of the music,through the observation of the form of video,with the help of music visualization and action visualization technology,to explore the relationship between performance posture and the actual sound effect of performance,to elaborate the influence of performance posture on the audience’s audio-visual perception,and finally to realize the exploration of body expression in the process of music performance.This article mainly consists of four chapters.The first chapter "Music Attitude and Expression" mainly introduces the concepts of music attitude,embodied cognition theory and music expression.The second chapter,"audio-visual-based sample selection",is an experimental report on the selection of typical music segments.In this experiment,30 students with upper tones were selected as subjects,and they were equally divided into two groups: "audio-visual group" and "auditory group".The differences between the two performance versions of the 18 music segments initially selected were judged and scored.The purpose was to select more scientific and representative music segments as the source of music segment materials for performance analysis in chapters 3 and 4.The third chapter "body expression in music performance" is to analyze the two performance versions from macro and micro dimensions,and find out the common expression and individual expression of the two performers in the performance of these music segments,and then discuss the body expression hidden in the performance process.The fourth chapter,"the influence of performance posture on visual hearing",is to analyze the performance posture of the two performers in the same music segment from the visual and auditory dimensions respectively,and then to obtain the similarities and differences of their posture performance.Combined with the sound value in the actual performance process and the audio-visual perception obtained by each participant,it finally draws the conclusions of the difference of posture on auditory perception,the influence of posture on vision and the influence of posture on hearing.Through the analysis of the above performance postures,three major problems aboutperformance postures are analyzed in detail: the relationship between performance postures and sound effects,the relationship between performance postures and common and individual interpretations,and the influence of performance postures on visual hearing.Furthermore,it reveals that the body not only acts as a bridge to transmit thoughts and express emotions,but also as a way to perceive and understand music and one of the important dimensions of musical expression,bringing more shock and rich audio-visual experience to the audience. |
