What guided him was chiefly instinct. He had, no doubt, considerable strict training in the science of counterpoint and composition. He wrote, as we know, not only harpsichord pieces, but operas and sacred music as well. In the sonatas there is a great deal of neat two-part writing, and an occasional flash of skill in imitations; but musical science is almost the last thing we should think of in connection with them. Rules are not exemplified therein. Burney relates, through L’Augier, that Scarlatti knew he had broken established rules of composition, but reasoned that ‘there was scarce any other rule worth the attention of a man of genius than that of not displeasing the only sense of which music is the object.’ And, further, that he complained of the music of Alberti and other ‘modern’ composers because it did not in execution demand a harpsichord, but might be equally well or perhaps better expressed by other instruments. But, ‘as Nature had given him [Scarlatti] ten fingers, and, as his instrument had employment for them all, he saw no reason why he should not use them.’ He might have included his two arms among his natural gifts. Certainly the free use he made of them in most of his sonatas marks a new and extraordinary advance in the history of keyboard music.
In the matter of form Scarlatti is not so strikingly an innovator as he is in that of style. He is in the main content to cast his pieces in the binary mold common to most short instrumental pieces of his day. Yet, as has already been suggested, the harmonic freedom which he enjoys within these relatively narrow limits is significant in the development of the sonata form; and even more significant is his distribution of musical material within them.
The binary form, such as we find it in the suites of Froberger and even in those of J. S. Bach, is essentially a harmonic structure. The balance and contrast which is the effect of any serviceable shape of music is here one of harmony, principally of tonic and dominant and dominant and tonic, with only a few measures of modulation for variety. There is, in addition, some contrast between that musical material which is presented first in the tonic key and that which appears later in the dominant. But, while we may speak of these materials as first and second themes or subjects, their individuality is hardly distinct and is, in effect, obliterated by the regularity and smoothness of style in which these short pieces are conventionally written. The composer makes no attempt to set them off clearly, one against the other. The entrance into the dominant key is almost never devised in such a way as to prepare the listener for a new musical thought, quite separate and different from that which he has already heard. The transitional passage from tonic to dominant emerges from the one and merges into the other, without break or distinctions.
In the matter of setting his themes in their frame, Scarlatti hardly differs from his contemporaries. His style, though free and varied, is in constant motion. But his genius was especially fertile in clean-cut figures; and when, as he often does, he combines two or three distinct types of these in one short piece, the music is full of thematic variety and sparkles with an animation which at times is almost dramatic.
Scarlatti is, indeed, hovering close to the sonata form in a great many of his pieces, and in one actually strikes it.[14] We shall, however, postpone a more detailed discussion of Scarlatti’s pieces in relation to the sonata form to the next chapter. The distribution of his musical material is quite whimsical and irregular, always more instinctive than experimental. It is chiefly by the quality of this material that he stands apart from his contemporaries, and as the founder of the free and brilliant pianoforte style.
There remains little to be said of the æsthetic worth of his music. During the years of his most vigorous manhood he was almost invariably a virtuoso. Sheer delight in tonal effects rather than more sober need of self-expression stimulated him. The prevalence of trumpet figures such as those which constitute the opening phrases of the eleventh and fourteenth sonatas in the Breitkopf and Härtel edition already referred to, suggests that he took a good deal of material ready-made from the operas of the day. Burney says there are many passages in which he imitated the melody of tunes sung by carriers, muleteers, and common people. But what he added to these was his own. A number of pieces are conspicuous by especially free modulation and expansion of form; and in these, technical effects are not predominant, but rather a more serious interest in composition. It has therefore been suggested that these pieces are the work of later years.[15] Though it is said that while in Spain he grew too fat to cross his hands at the harpsichord as was his wont in his youth, this physical restriction is not alone responsible for the mellowness and warmth of such pieces as the so-called Pastoral in D minor, familiar to audiences in Tausig’s elaborated transcription. A great number of his pieces are rich in pure musical beauty; and the freshness which exhales from all true musical utterance is and probably always will be theirs.
None of his contemporaries in Italy approached him in the peculiar skill which has made him conspicuous in the history of pianoforte music. Francesco Durante (1684-1755) and Nicolo Porpora (1686-1767), the great singing master, both wrote pieces for the harpsichord; the one, ‘sonatas’ in several movements, the other fugues; but their music lacks charm and can hardly be considered at all influential in the development of the art of writing for keyboard instruments. Domenico Alberti and P. D. Paradies will be considered in the following chapter.
II
The art of Couperin is flawless, the charm of his music not to be described. It has that quality of perfection with which Nature marks her smallest flowers. It is the miniature counterpart in music of a perfected system of living, of the court life of France under Louis XIV.
Scarlatti was a rover. He tried his fortune in Italy, in England, in Portugal and Spain. He won it by the exhibition of his extraordinary and startling powers. He was on the alert to startle, his tribute the bravas and mad applause of his excited hearers. He was the virtuoso in an old sense of the word, the man with his powers consciously developed to the uttermost. Bach, on the other hand, was an introspective, mighty man, immeasurably greater than his surroundings, fathomless, personal, suggestive. Between them stands Couperin, for the greater part of his life in the intimate service of the most brilliant court the world has ever seen, delicate in health, perfect in etiquette, wise and tender.
