Version of the Cellist Wilhellm Fitzenhagen-An homage of Tchaikovsky to the great admired example of Mozart and a challenge to the solo cellist: 'Rokoko-Variationen' the theme of which follows the style of 18th-century music closely demands a maximum of performing and technical brilliance from the solo cellist. The variations are musically connected by orchestral ritornellos which with regard to music and substance almost form a second sequence of variations.
