Although Beethoven himself did not think highly of his first piano concerto, considering it lacking in spirit and compositional innovation, he did write a new cadenza for this work many years later. By the time of his fourth piano concerto, Beethoven was a mature composer daring to innovate—the opening with piano chords broke the tradition of orchestral expositions. The second movement is even more unorthodox. The tenderness of a slow movement disappears, the orchestra-piano dialogue is blurred almost like a recitative. This novel concerto inspired many later pianists, from Brahms to Medtner, who all preferred this piece and composed their own cadenza.
