From 'Zelmira' by Gioacchino Rossini op. I would like to precede the report of the results of my research with an explanation of what is meant by 'form-integrating elements'. Bobrowicz's variations belong to the type of numbered variations, as a rule ornamental ones. In Bobrowicz' output, the latter usually plays the main part. Crucial points of the theme generally have strong influence on a particular variation, but there are exceptions from this rule.
Some variations show considerable independence in terms of motivic elaboration.
Taking this fact into account each thorough quotation of the theme's melody inside a variation cycle is noted as an additional form-integrating element. The time signature of the theme is not always kept by Bobrowicz in every variation. However, in such cycles we can find elements that smoothly connect the variations of different meters. In some cycles of Bobrowicz we can observe a tendency to connect two or more subsequent movements into a larger formal unity. My chief interest, therefore, lies exactly in these additional integrating elements.
