If we look at the original editions of the six works which were printed in Bach’s time, they speak in no uncertain tone of the taste of the age. From 1726 to 1730 appeared the “Klavierübung”—the first part, with the suites which are known as “Partiten.” In 1735 we have the second part of the Klavierübung, containing the Italian Concerto and the “Ouverture nach französischer Art” (also a suite). In 1739 appeared the third part, in which are found organ chorales along with four duets for two claviers. In these the distinction between organ and clavier is as feebly marked as it always was before the invention of the pianoforte. The fourth part, which appeared in 1742, contains the great Variations for clavicymbal with two keyboards. Besides these, in 1747 appeared the “Musikalisches Opfer,” in which the theme of Frederick the Great is elaborated; and, in 1752, two years after Bach’s death, was published the “Kunst der Fuge.” He could only venture on the printing of the “Kunst” in his later years, when the Bach fugue had made some way in the world. The “Musikalisches Opfer” came out under the protection of the King; all the other clavier-pieces which seemed to him likely to pay for the printing are of a lighter kind—suites and concertos “for the delight of amateurs,” as it stands on the title-page. The three types of the great Bach counterpoint—the miniature Invention, the free Toccata, and the absolute Fugue—then, as now, appealed to too select a circle to attain the popularity of dances and concertos.

If Bach’s greatness is in the former works stupendous, in the latter it is loveable. Here we learn to know his other side. It is his “other manner.” Here, instead of the severe canonic development of a theme, attention is paid to the voices as parts of a harmonious whole; he steps down from the cothurnus, and moves familiarly in pleasant comedy. Still, the contrapuntal conception is the basis of the structure; but simply harmonised floriations of melody are interwoven, so that the clavier almost rivals the arioso of a violin. Between the extremes of the first movement of the “Chromatic Fantasia,” with its free rhythms, arpeggios, recitatives, and song-passages, and of the second movement, the regular fugue—extremes which mark the two limits of Bach’s style—there is an endless abundance of methods of treatment, in which now the contrapuntal element and now the arioso takes the lead. We see Bach in this second group of his clavier-works, the suites and concertos, pass over into the enchanting fields of Italian sensuous music. But it is remarkable how he never loses for a single moment his unique depth and his insatiable delight in form. There is a very abyss between a suite of Bach, founded on the Eternities, and one of Handel’s, owing its popularity to the transitory charms of dexterous trivialities.

There are three great groups of Bach’s clavier-suites: the so-called Partiten, which appeared in print in his own life-time, the “English Suites,” and the “French Suites.” The Partiten, which were first published separately, must, as the earliest work of this author known to the public, have struck the whole world with bewilderment. It was the first bound of a unique genius, the elevation of a traditional form of art into quite unparalleled shapes, a storm of intellectual lightning in a region long regarded as exclusively owned by Frenchmen and Italians. Even to-day the Partiten belong to the most select class of clavier-literature; and I cannot for a moment conceive how they are not to be regarded as superior by many degrees to the English and French suites. In no book is the future of music more clearly foretold. To see in the B flat major corrente, Chopin; in the B flat major gigue, Schumann; in the C minor sinfonia, Beethoven; in the C minor Rondo and Capriccioso, Mendelssohn; in the A minor Scherzo, Mozart, is no mere enthusiastic fancy.

The Partiten outgrew the ordinary scheme of the suites (allemande, corrente, saraband, gigue) as Beethoven’s sonatas outgrew the old scheme of sonatas. They have given a new life and a new spirit to a traditional form. The suite, which at the end of the seventeenth century has become merely conventional, is so elevated by the spirit of Bach that it thenceforward stands in the world of actuality. Even Schumann selects a similar form for the expression of modern emotions. The suite having been thus despatched, the sonata is in similar fashion put into precise and regular form, to be transfigured later by Beethoven with the same modern spirit. Bach had the fortune and the genius to relegate the traditional suite into the past, and to see the conventional sonata dawning in the future. Thus with him the dance-piece and the free piece remained fresh and lively. Suite and sonata were only different external ways for reducing several pieces to unity. There, men took their stand on the old familiar series of dance-tunes, without ever thinking of the dances themselves; here, they found for the first movement a practical form, and, in the event, ranged the adagio, scherzo, and rondo together, just as their predecessors had used the saraband, minuet, and gigue. On this tendency to unity on the part of the clavier-pieces, from the first English variations, through Couperin’s Ordres, to Bach’s suites, Italian sonatas and German sonatas, Chopin’s Albums, Schumann’s Scenes, Liszt’s Epics, too much stress need not be laid. Even more than the orchestra, the clavier leans to short pieces, but the intellect demands some excuse for binding them together.

If we take a striking liveliness as the characteristic of the Partiten, we indeed find a feature in which they are distinguished from the French Suites, but which is far from exhausting their qualities. Solid melodies, humorous capriccios, enchanting dances, tuneful airs, everything is included in these works. In their pages we realise how the spirit of Bach strives to utter the very utmost of which it feels itself capable. And in these introductory preludes, toccatas, or symphonies, in these flowing allemandes, gliding correntes, heavy sarabands, filigree-worked gigues, in those numerous intermezzo movements, such as burlesques, rondos, airs, minuets, and passepieds, there are turns of genius, the form of which is impressed for ever on the mind. I think of the sweet running movements of the astonishing B flat major Gigue; of the brilliant structure of the C minor Capriccio, which concludes the Partita in place of a Gigue; of the D major aria, in which breathes the whole grace of the eighteenth century; of the bold and rhapsodical Saraband in D major; of the rich colouring of the introductory E minor Toccata; the rocking melody of the allemande, the sombre glow of the saraband, the wayward syncopations of the gigue.

The six English Suites, which we may certainly assume to have been put into juxtaposition by Bach himself, stand between the six printed Partiten and the six French Suites, whose combination was only probably, not certainly, due to Bach. They would seem to have been called “English” suites, because they were arranged for some Englishman; the original title was apparently “suites avec prélude.” For the English suites, like the Partiten, have each a fairly long introduction, fugal in style, but not conforming to the strictest laws of the fugue. The intermezzi, also, are as numerous as in the case of the Partiten. But that extreme intellectual severity is wanting; they are more graceful and polite. This character is especially noticeable in the introductory fugal movements and the intermediate dance pieces; and one who seeks rather a play of tone than grandeur of soul will perhaps find here a richer yield than in the Partiten. Neat, volkslied-like sarabands, ravishing bourrées, rococo gavottes, ornamental minuets, the exquisitely delicate passepied in E minor—these all lie so thick one on another, that one cannot recall a more sparkling album of dainty dances in the whole eighteenth century. It is true that in the Vienna school (as in the case of the younger[79] Muffat and others) there is in this class of dances a gentle soothing quality, which gives us the first hint of the coming beautiful Viennese dance-music; but they are, like those of Handel, too short in duration and too featureless for us to be able to return to them with the extraordinary affection with which we return to those of Bach. These are so rich in invention that they cannot in many centuries lose their flavour. The dancing underpart of the D major gavotte in the D minor suite, the multiform air of the D minor, E minor, and A minor sarabands, the filigree-counterpoint of the E minor Passepied, the extreme daring of the A minor bourrée, the transport of the A minor prelude, which even grows into a roundelay,—what a depth of originality is there in all these pieces, in which the repetitions so wonderfully satisfy the laws of the mind without becoming mechanical!

How the French Suites came by their name is hard to say. More French than the English suites they are certainly not, for they are quite as Bach-like as the latter. Without Preludes and without too many Intermezzi or “Doubles” (repetitions with variations), they are of astonishing variety. The Allemandes especially, as first movements in every suite, display such a manifoldness of form, that in fact nothing is left in common to them but the four-time beat. The song in the Saraband and the dance in the Intermezzi appear to the same effect as in the English suites, and a light tone runs through the whole. But the tone is lightest of all in the E major suite, which with its rolling allemande and courante, its singing saraband, its stiff and formal gavotte, its characteristic polonaise, its tricksy bourrée, and its cheerful gigue, is a perfect paradise of dainty devices. The flowing courante in it strikes our fancy; for it is precisely in the courantes of these suites with their heavy old-fashioned movements that we shall most often hit on the rare occasions on which we must regard Bach as already obsolete. The ornamentations tend to appear less befitting to us, scattered so profusely as they are in these movements. But to Bach, little as he could as yet succeed in emancipating himself from ornamentations, they were no longer such a matter of course as with the old French clavecinists. If we compare the different manuscripts of his works, we see the uncertainties and alterations. Bischoff, in his excellent critical edition of Bach’s clavier-music (Steingräber) has therefore only engraved large those ornamentations which were without doubt always played by Bach. Taste will fill them in in certain places on grounds of symmetry and “thematic”; but they are no longer bewildering in their profusion.
