and the Kromï Scene), cut one (The Cathedral of Vasiliy the Blessed), and recomposed another (the Terem Scene). The modifications resulted in the addition of an important prima donna role (Marina Mniszech), the expansion of existing female roles (additional songs for the Hostess, Fyodor, and the Nurse), and the expansion of the first tenor role (the Pretender). Mussorgsky augmented his adaptation of Pushkin's drama with his own lyrics, assisted by a study of the monumental History of the Russian State by Karamzin, to whom Pushkin's drama is dedicated. The Revised Version was finished in 1872 (vocal score, 14 December 1871; full score 23 June 1872), and submitted to the Imperial Theatres in the autumn. Most Mussorgsky biographers claim that the directorate of the Imperial Theatres also rejected the revised version of Boris Godunov, even providing a date: 6 May 1872 (Calvocoressi), or 29 October 1872 (Lloyd-Jones). Recent researchers point out that there is insufficient evidence to support this claim, emphasizing that in his revision Mussorgsky had rectified the only objection the directorate is known to have made. In any case, Mussorgsky's friends took matters into their own hands, arranging the performance of three scenes (the Inn and both Sandomierz scenes) at the Mariinsky Theatre on 5 February 1873, as a benefit for stage manager Gennadiy Kondratyev. César Cui's review noted the audience's enthusiasm: The success of this performance led V. Bessel and Co. to announce the publication of the piano vocal score of Mussorgsky's opera, issued in January 1874. Premiere The triumphant 1873 performance of three scenes paved the way for the first performance of the opera, which was accepted for production on 22 October 1873. The premiere took place on 27 January 1874, as a benefit for prima donna Yuliya Platonova. The performance was a great success with the public. The Mariinsky Theatre was sold out; Mussorgsky had to take some 20 curtain calls; students sang choruses from the opera in the street. This time, however, the critical reaction was exceedingly hostile [see Critical Reception in this article for details]. Initial performances of Boris Godunov featured significant cuts. The entire Cell Scene was cut from the first performance, not, as is often supposed, due to censorship, but because Nápravník wished to avoid a lengthy performance, and frequently cut episodes he felt were ineffective. Later performances tended to be even more heavily cut, including the additional removal of the Kromï
