In the nineteenth century, Tchaikovsky was an important, representative composer in Russia and succeeds the prior previous musical development of Russia. Back then, I think this what was mean type of works were quite fundamental. In 1876, he had written the cello piece, ¡§Variation on a Theme Rococo,¡¨ and dedicated to a cellist, Fitzenhagen. Fitzenhagen changed the sequence for the variations, deleted and rewrote some segments. As a result, it made the version different from the one that was composed by Tchaikovsky. The version edited by Fitzenhagen was published, and it has been played until now. This lecture-recital document contains the following two main sections.
