One of Clara Schumann's difficulties with Liszt stemmed from a philosophical difference in performance practice. He believed that the artist, through physical and emotional performance, interpreted music for the audience. When he performed, Liszt flailed his arms, tossed his head, and pursed his lips., inspiring a Lisztomania across Europe which has been compared to the Beatlemania of female fans of The Beatles over a century later. Clara, in contrast, came to believe that the personality of the musician should be suppressed so that the composer's vision would be clearly evident to listeners.
