Musicology Annotation << Back «Russian true story» by Сaterino Сavos Alexandra E. Maximova The article is devoted to the study of documentary sources of the little-known work of C.A. Cavos – music to the drama of A.A. Shakhovskoy «The Falcon of Prince Yaroslav of Tver, or the Prisoner on a White Horse» (1823). This work refers to the numerous musical and theatrical opuses of Cavos to the «Russian» plot. The surviving libretto allows not only to restore the plot of the play, defi ned by Shakhovskoy as «Russian true story» (based on the ancient legend of the marriage of Grand Duke Yaroslav), but also to clarify the history of the production of the play, to restore the names of the characters. The musical sources – a tutor and a set of orchestral voices – were studied. As a result, the location of musical numbers in the play was restored; revealed reliance on Russian folklore themes, contrasting with the alien «janissary» music that characterizes the opponents of the prince. Autocytata was found: Cavos transferred to this work two large fragments from his opera on the libretto by Shakhovskoy «Ivan Susanin» (1815). A signifi cant place in the article is given to the ballet scene staged by Ch. Didlo, in which the confl ict of Russian soldiers with «barbarians» – Tatar heroes and German crusaders is resolved. The combination of the libretto and musical sources is the first step to the reconstruction of the work. Keywords: music for drama, ballet, Cavos, Shakhovskoy, Didlo, Russian musical theater.
