| This article takes Schubert’s impromptu Op.142 No.3 as the research object,expounds the origin and development of this genre based on his life experience and the background of the era at that time,and analyzes the music ontalogy from threeaspects:the motivation and development mode of the theme,the layout and structuual characteristics of tonality,and the musical style that blends classical and romantic,so as to better grasp the integrity and independence of the work.Then,professional music analysis software is used to compare the performance audio of three pianists with distinct performance styles,namely,Brendel,Horowitz,and Uchida,to generate intuitive data charts based on speed and strength.In this way,similarities and differences between different versions are discovered and considered,and experience and methods are gained.Finally,on the basis of comparative analysis,I will elaborate on my experience in performing this piece of work from four aspects:structure,hierarchy,touch of keys,and pedal,in order to further improve my technical ability and performance. |
