While, however, we may with propriety recognize the lack of personal ardor in Saint-Saëns that reduces the song element in his music to a minimum, it would be a sad mistake to exaggerate the limitation or to forget that from another and perhaps an equally valid point of view he is a great musician. However he may fall short as a melodist, he is a past-master of rhythm and harmony, spheres in which feeling counts for less, logic for more. His harmonic style is eminently lucid. To him a chord is part of an organism, not a bit of color or a phase of feeling. A series of chords has for him all the tendency, the direction, and the self-fulfillment of a sentence of words; to omit or to change one would be like striking out a predicate or an object--the sentence would not parse. He uses most those chords which point in a definite direction, which carry in themselves, so to speak, the indication for their fulfillment--the dominant and secondary sevenths, and suspensions of triads. He avoids the vague and the ambiguous. And although he is a lover of novel harmonic effects, and an ingenious inventor of them, the novelty is always a new form, not a new formlessness. His modulation, too, is of an extreme clarity: he never falls into a new key, so to speak, as Dvořák does; he proceeds thither. But even more striking than the clearness of his harmony is the trenchant perspicuity of his rhythm. The sense of rhythm is perhaps the prime criterion of intellectuality in a composer. For just as determinations of accent and measure, such as occur in the dances of the most primeval savages, were undoubtedly the earliest means of formulating the cries and wails of emotion which underlie all musical expression, so throughout musical history rhythm has been the chief formative or rationalizing agent, and a vivid sense of it has always characterized the more intellectual musicians. The dreamers and the sentimentalists are never fastidious of accent; it is the clear, active minds who delight in precise meter. Quite inevitable to a man of Saint-Saëns's temperament, then, is the instinct for strong, various and subtle rhythms that his compositions reveal at every page. One discerns it in his fondness for pizzicato effects and for the percussion instruments, both of which emphasize the accent. And his devotion to the piano, which he uses more in combination with other instruments than almost any other composer, is doubtless due to the fact that it compensates for its lack of sustained tone by a special incisiveness of attack. Another significant peculiarity is the short groups of repeated notes that occur so often in his writings as to be a mannerism. They are found, for example, in the fourth of his Variations on a Theme of Beethoven, opus 35, in the «scherzando» section of «Africa,» at the opening of the Trio, opus 92, in the accompaniment of the well-known air from «Samson et Dalila,» «Mon cœur s'ouvre à ta voix,» and in the third of the Six Études, opus 52.
