For English speakers, the popular title of "Hammerklavier" that Beethoven's sonata No. 29 bears may seem rather rude. That title could suggest the idea of a sonata in which the pounding of the piano is a necessity. Nothing could be further from that.
The title, which the work shares with the preceding sonata, is simply the German word for "pianoforte." Beethoven wanted to thank the English piano builder Broadwood, who had recently sent him a modern piano with swinging strings. It is for this modern piano that the sonata is written: Große Sonate für das Hammerklavier, its full title.
It is followed by a brief scherzo of just under three minutes.
In opposition, the subsequent adagio (which here goes as the third movement and not second as was common) is one of the longest slow movements in all piano literature, about twenty minutes, and one of the most dramatic written by Beethoven: appassionato e con molto sentimento, the master noted.
The last movement is the most ambitious, the one containing the famous fugue, in three voices, whose theme or subject extends for ten bars (min 34:15, in this version) and not the typical two or three of the baroque fugue, thus raising the technical and interpretative demand to incredible extremes.
