CHAPTER VI. BACH THE COMPOSER (continued)
Bach's treatment of harmony and modulation powerfully influenced his melody. The strands of his harmony are really concurrent melodies. They flow easily and expressively, never engross the hearer's attention, but divide his interest, as now one now the other becomes prominent. Even when they are noticeable they seem obscured by the melodic parts that accompany them—I say “seem obscured,” for if the hearer is sufficiently instructed to distinguish the several melodies in the ensemble he will discover them to be more clearly defined by their accompaniment.
The combination of several melodic lines obliges the composer to use devices which are unnecessary in homophonic music. A single melody can develop as it pleases. But when two or more are combined each must be so delicately and cleverly fashioned that it can be interwoven with the others in this direction and in that. And here we detect one at least of the reasons why Bach's melodies are so strangely original, and his tunes so clearly distinguishable from those of other [pg 81] composers. Provided that novelty does not degenerate into eccentricity or extravagance, and that clearness and facility of expression march with agreeableness, a composer's meritoriousness is proclaimed in his originality.[150] The one drawback is that the ordinary hearer cannot appreciate melodic beauties which are patent only to the expert.
But Bach's melodies are not invariably so handicapped. They are always original, it is true. But in his free compositions the melodies are so natural and spontaneous that, while they sound differently from those of other composers, their naturalness, and the sincerity of feeling that inspires them, make them intelligible to every listener. Most of the Preludes in the Well-tempered Clavier as well as a number of movements in the Suites are of this character.
Bach's melody, then, bears the unmistakable stamp of originality. And so does his passage work, as it is called. Such novelty, originality, and brilliancy are not found in any other composer. Examples are to be found in all Bach's Clavier works. But the most striking and original are in [pg 82] the Great Variations,[151] in the first Part of the Clavierübung,[152] in the English Suites,[153] and the Chromatic Fantasia.[154] In the last particularly Bach's fertility impresses us. The greater part of its passage work is in the form of harmonic arpeggios whose richness and originality match the chords they represent.
In order to realise the care and skill Bach expended on his melody and harmony, and how he put the very best of his genius into his work, I need only instance his efforts to construct a composition incapable of being harmonised with another melodic part. In his day it was regarded as imperative to perfect the harmonic structure of part-writing. Consequently the composer was careful to complete his chords and leave no door open for another part. So far the rule had been followed more or less closely in music for two, three, and four parts, and Bach observed it in such cases. But he applied it also to compositions consisting of a single part, and to a deliberate experiment in this form we owe the six Violin and the six Violoncello Solo Suites,[155] [pg 83] which have no accompaniment and do not require one. So remarkable is Bach's skill that the solo instrument actually produces all the notes required for complete harmony, rendering a second part unnecessary and even impossible.
Bach's melody never palls on us, because of the presence in it of those qualities to which I have referred. It remains “ever fair and young,” like Nature herself. In his earlier works, in which we find him still in bondage to the prevailing mode, there is a good deal that to-day seems antiquated. But when, as in his later works, he draws his melody from the living wells of inspiration and cuts himself adrift from convention, all is as fresh and new as if it had been written yesterday. Of how many compositions of that period can the same be said? Even the works of ingenious composers like Reinhard Keiser[156] and Handel have become old-fashioned sooner than we or their composers might have supposed. Like other caterers for the public, they were obliged to pander to its taste, and such music endures no longer than the standard which produced it. Nothing is more inconstant and fickle than popular caprice and, in general, what is called fashion. It must be admitted, however, that Handel's Fugues are not yet out of date, [pg 84] though there are probably few of his Arias that we now find agreeable.[157]
Bach's melody and harmony are rendered still more distinctive by their inexhaustible rhythmic variety. Hitherto we have discussed his music merely subjectively as harmony and melody. But to display vivacity and variety music needs to be uttered with rhythmic point and vigour. More than those of any other period composers of Bach's time found no difficulty in this, for they acquired facility in the management of rhythm in the “Suite,” which held the place of our “Sonata.” Between the initial Prelude and closing Gigue the Suite includes a number of characteristic French dance measures, whose rhythm is their distinguishing characteristic. Composers of Bach's day, therefore, were familiar with measures and rhythms which are now obsolete. Moreover skilful treatment was necessary in order that each dance might exhibit its own distinctive character and swing. Herein Bach exceeded his predecessors and contemporaries. He experimented with every kind of key and rhythm in order to give variety and colour to each movement. Out of his experience he acquired such facility that, even in [pg 85] Fugue, with its complex interweaving of several parts, he was able to employ a rhythm as easy as it was striking, as characteristic as it was sustained from beginning to end, as natural as a simple Minuet.
The source of Bach's astonishing pre-eminence is to be sought in his facile and constant application of the methods we have discussed. In whatever form he chose to express himself, easy or difficult, he was successful and seemingly effortless.[158] There is not a note in his music that does not suggest consummate ease of workmanship. What he sets out to do he concludes triumphantly. The result is complete and perfect; no one could wish for a single note to be other than it is. Some illustrations will make my point clearer.
Carl Philipp Emmanuel, in the preface to his father's Vierstimmige Choralgesänge (“Four-part Hymn-tunes”), which he edited,[159] says that [pg 86] the world was accustomed to look for nothing but masterpieces from Bach. Some reviewers thought this praise exaggerated. But if the term “masterpiece” is restricted to works written during the years of Bach's maturity[160] it is nothing less than the truth. Others have produced masterpieces in various forms which may be placed honourably by the side of his. For instance, certain Allemandes, Courantes, etc., by Handel and others are not less beautiful, though less richly wrought, than Bach's. But in Fugue, Counterpoint, and Canon he stands alone, in a grandeur so isolated that all around him seems desert and void. No one ever wrote Fugues to compare with his; indeed, persons unacquainted with them cannot imagine what a Fugue is and ought to be. The ordinary Fugue follows a rule of thumb development. It takes a theme, puts another beside it, passes them into related keys, and writes other parts round them over a Continuo. Certainly this is Fugue: but of what merit? Persons who know no other not unnaturally hold the whole species in little esteem, and the player who hopes to make such commonplace material convincing will need all his skill and imagination.
Bach's Fugue is of quite another kind. It presents all the characteristics we are accustomed to [pg 87] in freer musical forms: a flowing and distinctive melody, ease, clarity, and facility in the progression of the parts, inexhaustible variety of modulation, purest harmony, the exclusion of every jarring or unnecessary note, unity of form and variety of style, rhythm, and measure, and such superabundant animation that the hearer may well ask himself whether every note is not actually alive. Such are the properties of Bach's Fugues, properties which excite the admiration and astonishment of all who can appreciate the intellectual calibre their composition demands. How great a tribute of homage is due to work of this kind, which exhibits all the qualities which lend distinction to compositions in other musical forms! Moreover, while all Bach's Fugues of his mature period have the foregoing properties in common, each is endowed with peculiar excellencies of its own, has its own distinctive individuality, and displays a melodic and harmonic scheme in keeping with it. The man who can play one of Bach's Fugues is familiar with, and can play, one only; whereas knowing one, we can perform portfolios of Fugues by other performers of Bach's period.
To what a height was the art of Counterpoint carried by Bach's genius! It enabled him to develop out of a given subject a whole family of related and contrasted themes, of every form and design. It taught him to develop an idea logically [pg 88] from the beginning to the end. It gave him such a command of harmony and its infinite combinations that he could invert whole themes, note by note, in every part, without impairing in the least the flow of melody or purity of his harmony. It taught him to write in canon at all intervals and in movements of all kinds so easily and naturally that the workmanship is not perceptible and the composition sounds as smoothly as though it were in the free style. Lastly, it has given to posterity a legacy of works immensely various, which are, and will remain, models of contrapuntal form as long as music endures.[161]
I have written exclusively so far of Bach's Clavier and Organ work. But in its expression music has two branches, instrumental and vocal, and as Bach excels in both of them, the reader will desire to hear somewhat respecting his vocal writings.
It was at Weimar that Bach first had occasion to write for the voice,[162] upon his appointment to [pg 89] the Kapelle, which imposed on him the provision of music for the ducal chapel. His church music, like his Organ works, is devout and serious, and in every respect what church music ought to be. He makes a point also of not elaborating individual words, which leads to mere trifling, but interprets the text as a whole.[163] His choruses invariably are magnificent and impressive, and he frequently introduces Chorals into them,[164] making the other parts accompany their Cantus fugally, as was the practice in a Motet. As elsewhere in his works, the harmonic structure of his voice parts and instrumental accompaniment is rich. The declamation of the recitatives is expressive, and the latter have fine Continuo parts.[165] In his Arias, hardly one of which is not beautiful and expressive, Bach seems to have been handicapped by the inefficiency of his singers and instrumentalists, who constantly complained of the difficulty of his music. If he had been fortunate enough to have capable performers the merits of his church music [pg 90] would have been established and, like his other works, they would still be sung and admired; for they contain treasures which deserve immortality.[166]
Among the works composed at Leipzig I single out two Cantatas, one of which was performed at Cöthen at the funeral of Bach's beloved Prince Leopold, and the other in St. Paul's Church, Leipzig, on the occasion of the funeral sermon in honour of Christiana Eberhardine, Queen of Poland and Electress of Saxony.[167] The first contains double choruses of uncommon magnificence and most affecting sentiment.[168] The second has only four-part choruses, but they are so delightful and fresh that he who begins the work will not pause till he has reached the end of it. It was written in October 1727.
Bach also composed a great number of Cantatas, chiefly for the choir of St. Thomas' School, Leipzig.[169] [pg 91] The choir ordinarily numbered fifty singers, and sometimes more, over whose musical training Bach presided like a father. He practised them so hard in Cantatas for single and double chorus that they became excellent singers. Among these works are some which, in profundity of conception, magnificence, richness of harmony and melody, and animation, surpass everything of their kind. But, like all Bach's works, and in common with other masterpieces, they are difficult to perform and need a numerous orchestra to produce their full effect.
Such are Bach's most important vocal compositions. [170] In minor forms of the art, morceaux for social entertainments and the like, he wrote little,[171] though he was of a most sociable disposition. For instance, he is said never to have composed a song.[172] And why should he? They produce themselves so spontaneously that there is little call for genius to aid their gestation.
