The solo brings its own protagonist aura, which is impressive. Solo is a form of performance that fully embodies individual singing skills, and it is a vocal performance that pays attention to individual expression. Solo performance is particularly important for the interpretation of personality, because without a unique personality tone and singing style, every soloist will present the same performance, which is undoubtedly lacking and eventually eliminated by society. Therefore, in the solo performance, the soloist should fully tap his own personality characteristics while honing his singing skills, so as to leave a deep impression on the audience in the performance.
