The evolution of music performance styles in the 20th century gave rise to trends stemming from RMP, MSP, and HIP. Within this evolution, certain performers exhibited distinctive and personalized style choices. Using Horowitz’s reimagined version of Liszt’s Danse Macabre as a case study in piano music, the author delves into aspects such as the composer's departure from authenticity, the extreme manifestation of personal style, the dichotomy in self-expression and evaluation. By examining his departure from the conventional MSP and HIP styles, along with the intense expression of his unique style, the exploration culminates in an examination of the controversy surrounding these expressions in performance practice, ultimately shaping Horowitz's music performance style preferences.
