By this time it will be clear enough that this was no puling complainer, but a delicate, high nature of great emotional intensity, subjected to a cruel interaction of temperament and circumstances, and yet capable of nobly constructive artistic work. His life, candidly examined, reveals modesty, dignity, elevation of ideal and of character. Yet it does illustrate, too, in many ways, that lack of emotional balance which underlies the peculiar quality of his music.
His mere method of approaching his art, in the first place, is significant. All his early efforts, as we have seen, were operas; he wrote altogether ten operas, and the Pathetic Symphony is the last fruit of a genius dramatic rather than symphonic. At thirty Tschaïkowsky was unable to read orchestral scores with ease, and preferred to study the classics through four-hand arrangements, while his distaste for the purest form of music was so great that he protested he could hardly keep awake through the performance of the masterly A-minor Quartet of Beethoven. This attitude toward the string quartet, which is in music what engraving or etching is in representative art, is very anomalous in a young composer, and shows so disproportionate an interest in the merely expressive side of music that it is hard to understand how Tschaïkowsky ever became so great a plastic master as his last two symphonies, for all their freight of passion, show him to be.
He never, in fact, wholly outgrew certain peculiarities which are direct results of his emotional instability, his slavery to mood. His persistent use of minor keys, for example, is, as the doctors say, symptomatic. The minor is naturally the medium of vague, subjective moods and fantasies, of aspiration, longing, and doubt; it is the vehicle of morbidly self-bounded thoughts, whose depressing gloom is equalled only by their seductive and malign beauty. Such thoughts we find too often in Chopin, Grieg, and, it must be added, in Tschaïkowsky. Of the first thirty songs he wrote, seventeen are in the minor mode. Of course too much should not be argued from a detail of this sort, but the major system is so naturally the medium of vigorously objective thought that we instinctively suspect the health of a mind which harps continually upon the minor. By a somewhat similar tendency towards self-involution, the natural result of intense emotionality, Tschaïkowsky inclines to monotony of rhythm; he gets hypnotized, as it were, by the regular pulsation of some recurring meter, and he continues it to the verge of trance. An example is the long pedal-point on D, in the curious 5-4 measure of the second movement of the Pathetic Symphony. This is like the wailing and rocking of the women of a savage tribe over the death of a warrior; it is at once wild and sinister. But perhaps the most striking evidence of this servitude to passion we are trying to trace in Tschaïkowsky is his constant use of climax. It seems to be quite impossible for him to preserve a mean-tone; he is always lashing himself into a fury, boiling up into a frenetic fortissimo, after which he lapses into coma until some phrase of melody or impulse of rhythm jostles his imagination again, and he presses on toward a new crisis. The effect of these cumulative whirlwinds of passion is often tremendous, is unique, indeed, in music; yet one longs sometimes in the midst of them for a less turbulent attitude, for the equable beauty of Bach or Mozart. The atmosphere is surcharged. One feels that this noble but willful spirit has sat too long in the close chamber of personal feeling, that one must throw wide the windows and let in the fresh winds of general human existence.
