His sentiment for Harmony aided him to turn the pleasant stories of chivalry and capricious jesting into poetry, and lesser erotic or narrative and argumentative poetry into more complex poetry, to accomplish the passage and ascent from the minor works to that which is truly great, to mediate the immediate, by transforming his various sentiments in the manner that we are about to consider. CHAPTER V THE REALISATION OF HARMONY The first change to manifest itself in them so soon as they were touched by the Harmony which sang at the bottom of the poet's heart, was their loss of autonomy, their submission to a single lord, their descent from being the whole to becoming a part, their becoming occasions rather than motives, instruments rather than ends, their common death for the benefit of the new life. The magical power which accomplished this prodigy was the _tone_ of the expression, that self-possessed, lightness of tone, capable of adopting a thousand forms and remaining ever graceful, known to the old school of critics as "the confidential air," and remembered among the other "properties" of the "style" of Ariosto. But not only does his whole style consist of this, but since style is nothing but the expression of the poet and of his soul, this was all Ariosto himself and his harmonious singing. This work of disvaluation and destruction is to be detected in the expressive tone in the proems to the separate cantos, in the digressive argumentations, in the observations interjected, in the repetitions, in the use of vocables, in the phrasing and the arrangement of periods, and above all in the frequent comparisons that form pictures which rather than intensifying the emotion, cause it to take a different path, in the interruptions to the narrative, sometimes occurring at their most dramatic point, in the nimble passage to other narratives of a different and often opposite nature. Yet the palpable part of this whole, what it is possible to segregate and to analyse as elements of style, forms but a small part of the impalpable whole, which flows along like a tenuous fluid, and since it is soul, we feel it with our soul, though we cannot touch it with our hands, even though they be armed with scholastic pincers. And this tone is the often noted and named, but never clearly defined _irony_ of Ariosto; it has not been well-defined, because described as a kind of jesting or mockery, similar or coincident with what Ariosto sometimes employed in his descriptions of knightly personages and their adventures. It has thus been both restricted and materialised, but what we must not lose sight of is that the irony is not restricted to one order of sentiments, as for instance those of knighthood or religion, and so spares the rest, but encompasses them all, and thus is no futile jesting, but something far more lofty, more purely artistic and poetical, the victory of the dominant sentiment over all the others.
