===Variation 28: ''Allegro''===

Von Bülow sees this as the close of the third main division of the work: "This Variation ... must be hammered out with wellnigh raging impetuosity... More delicate shading would not be in place – at least in the First Part". (von Bülow)

Tovey writes:

{{quote|After the twenty-eighth variation has brought this stage of the work to an exhilarating close, Beethoven follows Bach's example .... at precisely the same stage (Variation 25) in the Goldberg Variations, and boldly chooses the point at which he shall enlarge our expectations of further developments more surprisingly than ever before. He gives no less than three slow variations in the minor mode, producing an effect as weighty (even in proportion to the gigantic dimensions of the work) as that of a large slow movement in a sonata.<ref name="Tovey, Donald Francis p. 131"/>}}

Brendel points out that as of 1819 there was a single C&nbsp;minor variation (No. 30) and that the late additions of Nos. 29 and 31 expanded the use of the key into "a larger C&nbsp;minor area".<ref name="Brendel, Alfred p.52"/> Brendel's title for this variation is ''The rage of the jumping-jack''.
