“No fan of the Romantic ‘showpiece’ concerto with a soloist doing star turns in front of a back-up orchestra, Brahms produced what Ludwig Finscher called a ‘symphonic concerto’ with the orchestra an equal partner,” (Mercury Orchestra). “He wrote the concerto (1859) for himself; if the piano part is difficult and showy, it is because it demands the physical dexterity and strength that he possessed. The work is in three movements and uses a ‘classical’ orchestra with four prominent French horns—an instrument that would be a Brahms trademark in years to come.”
In the concerto’s third movement, Rondo: Allegro non troppo, “Brahms changes the mood entirely with a vigorous finale modeled on the rondo finale of Beethoven’s Piano Concerto No. 3, a work he knew well. The form is ABACABA, with A upbeat and heavily bubbling, B a flowing variant of A, and C a short forceful section turned loose by the horns. The last A section is thickly developed, complex, and includes a fugue in the strings … the two cadenzas have structural functions, the first leading to a key change, the second to a triumphant coda that includes some thrilling chord changes.”
The movement begins solidly in D minor, but by its end has shifted into its cadenza in D major via a meandering path. By the 10:30 mark, the orchestra gradually tapers to nothing as the piano is featured, only to dramatically re-appear for the very ending of the movement.
