Wilhelm Kempff
Cadenza: Beethoven wrote one cadenza for this movement. The cadenza Beethoven wrote is at times stormy and ends on a series of trills that calm down to pianissimo. Many other composers and pianists, such as Fazil Say, Wilhelm Kempff, Clara Schumann, Franz Liszt, Ignaz Moscheles (in which his cadenza was misattributed to Johannes Brahms), and Charles Alkan have written alternative cadenzas.
