There are many repertoire of dazzling skills in classical music, and there are multiple forces to promote dazzling skills in the development of history. Sometimes, it is the composer who wants to test the limits of sound, writing a passage that the performer at that time generally cannot play for the sake of melody or harmony. Sometimes, it is the composer who does not know enough about a solo instrument to think rationally from the point of view of playing, so he writes a piece that is difficult or even impossible to play. Sometimes, it is the performer who takes the initiative to pursue a breakthrough, asking for music that could not be performed in the past, so as to highlight the difference between himself and other performers.
The statement 'The performer has to perform to the limit because of the requirements of the music' is not in line with the meaning of the text with regard to the driving force of the dazzling skills of music.
