The initial Sunday in December, 1878, at Paris, was a memorable afternoon for me. (I was then writing "special" stories to the Philadelphia _Evening Bulletin_, and the rereading of my article in print has refreshed my memory.) I heard for the first time the music of Rimsky-Korsakof, also the name of Modeste Moussorgsky. The symphonic poem, Sadko, was hissed and applauded at a Pasdeloup concert in the Cirque d'Hiver, for the new music created, on the whole, a disturbing impression. To quiet the rioting in the audience--it came to shouts and fisticuffs--the conductor, Jacques Pasdeloup (whose real name was Jacob Wolfgang) played Weber's Invitation to the Valse, arranged by Berlioz, which tribute to a national composer--neglected when alive, glorified after death--put the huge gathering of musical "chauvinistes" into better humour. Sitting next to me and rather amused, I fancy, because of my enthusiasm for Sadko, was a young Russian, a student at the Sorbonne. He liked Rimsky-Korsakof and understood the new music better than I, and explained to me that Sadko was too French, too much Berlioz, not enough Tartar. I didn't, at the time, take all this in, nor did I place much credence in his declaration that Russia had a young man living in St. Petersburg, its greatest composer, a truly national one, as national as Taras Boulba, or Dead Souls. Moussorgsky was his name, and despite his impoverished circumstances, or probably because of them, he was burning the candle at both ends and in the middle. He had finished his masterpieces before 1878. I was not particularly impressed and I never saw the Russian student again though I often went to the Sorbonne. I was therefore interested in 1896 when Pierre d'Alheim's monograph appeared and I recalled the name of Moussorgsky, but it was only several seasons ago and at Paris I heard for the first time both his operas. In 1889 Rimsky-Korsakof directed two concerts of Russian music at the Trocadero and Paris fell in love with his compositions. He not only orchestrated the last opera of his friend Moussorgsky, but also Dargomyjski's The Stone Guest, and with the assistance of his pupil, Glazounow, completed the score of Prince Igor, by Borodine. He was an indefatigable workman, and his fame will endure because of "handling" of gorgeous orchestral tints. He is an impressionist, a stylist, the reverse of Moussorgsky, and he has the "conscience of the ear" which his friend lacked. Praised by Liszt, admired by Von Buelow, he revealed the influence of the Hungarian. Profound psychologist he was not; an innovator, like Moussorgsky he never would have been; the tragic eloquence vouchsafed Tschaikovsky was denied him. But he wielded a brush of incomparable richness, he spun the most evanescent and iridescent web, previous to the arrival of Debussy: he is the Berlioz of Russia, as Moussorgsky is its greatest nationalist in tone.
