In _A Life for the Tsar_ Glinka conceived the idea, interesting in itself, of contrasting the characters of the two nations by means of their national music. To this end he devotes the whole of the second act entirely to the Poles. Here it seems to me that he is far less successful than with any other portion of the work. Some critics have supposed that the composer really wished to give an impression of the Poles as a superficial people literally dancing and revelling through life, and possessed of no deeper feelings to be expressed in music. But Glinka was too intelligent a man to take such naïve views of national character. It seems more probable that not being supersaturated with Polish as he was with Russian folk-music, he found it difficult to indicate the personality of the Pole in anything but conventional dance rhythms. This passes well enough in the second act, where the scene is laid at a brilliant festival in the Polish capital, and the ballroom dances which follow constitute the ballet of the opera. But in other parts of the work, as, for instance, when the Polish soldiers burst into Sousanin's cottage and order him to act as their guide, the strains of a stately polonaise seem distinctly out of place; and again, when they have lost their way in the forest and their situation is extremely precarious, they express their alarm and suspicion in mazurka rhythm. The polonaise, cracoviak, the valse in 6-8 time and the mazurka and finale which form the ballet are somewhat ordinary in character, but presented with a charm and piquancy of orchestration which has made them extremely popular. The representative theme of the Poles, a phrase from the polonaise, hardly suggests the part they play in the opera--their evil designs upon Moscow and the young Michael Feodorovich, about which they sing in the succeeding chorus. But others seem to find this music more impressive, for, says M. Camille Bellaigue, "even when restricted to strictly national forms and formulas, the Russian genius has a tendency to enlarge them. In the polonaise and especially in the sombre and sinister mazurka in _A Life for the Tsar_ Glinka obtains from local rhythms an intimate dramatic emotion.... He raises and generalises, and from the music of a race makes the music of humanity."
