The first of the three added variations is No. 1, a "mock-heroic" march which immediately follows Diabelli to open the set dramatically, echoing in the right hand the tonic triad of the theme while the left hand simply walks down in octaves Diabelli's descending fourth. No. 2 even maintains the repeated root-position triad, demonstrating the intent to keep the beginning of the set somewhat anchored. Afterwards however, Diabelli is barely recognizable until Variation 15, the second structural variation, a brief, lightweight piece conspicuously inserted between several of the most powerful variations (Nos. 14, 16 and 17). It recalls and caricatures the original waltz by means of its prosaic harmony. The third and final structural variation, in Kinderman's analysis, is No. 25, which shifts Diabelli's monotonous rhythm from the bass to the treble and fills the bass with a simple figure endlessly repeated in a "lumbering caricature". Arriving comically after the sublime Fughetta's arresting conclusion, it opens the concluding section of the series, from the total unraveling of the following major variations and descent into minor, to the determination of the fugue, to the transcendence of the minuet.
