“Christine Nilsson is having a great triumph here. I have seen her twice, and I must own she has made great progress as an actress since I heard her for the first time in Paris. As regards singing, Nilsson stands alone. When she opens her mouth one does not hear anything remarkable at first; then suddenly she takes a high C, or holds a sustained note pianissimo, and the whole house thunders its applause. But with all her good qualities she does not please me nearly so well as Artôt. If the latter would only return to Moscow I should jump for joy.” During the Christmas holidays Tchaikovsky was called unexpectedly to St. Petersburg to hear the verdict of the committee upon his opera, _The Oprichnik_. The committee consisted of the various Capellmeisters of the Imperial Theatre and Opera: Napravnik (Russian opera), Bevignani (Italian opera), Rybassov (Russian plays), Silvain Mangen (French plays), Ed. Betz (German plays), and Babkov (ballet). With the exception of Napravnik, Tchaikovsky had no great opinion of these men, and considered them much inferior to himself as judges of music. It seemed to him particularly derogatory to have to appear before this Areopagus in person. He did his best to avoid this formality, but in vain. The meeting which he dreaded so much passed off quite satisfactorily. _The Oprichnik_ was unanimously accepted. During this visit to St. Petersburg Tchaikovsky was frequently in the society of his friends of the “Invincible Band”; and it was evidently under their influence that he took a Little Russian folksong as the subject of the Finale of the Second Symphony. “At an evening at the Rimsky-Korsakovs the whole party nearly tore me to pieces,” he wrote, “and Madame Korsakov implored me to arrange the Finale for four hands.” On this same occasion Tchaikovsky begged Vladimir Stassov to suggest a subject for a symphonic fantasia. A week had hardly passed before Stassov wrote the following letter:-- “ST. PETERSBURG, “_December_ 30_th_, 1872 (_January_ 11_th_, 1873).
