Chapter XI

The Christmas Oratorio--The Magnificat--The Lost

Works--Instrumental Works--Bach’s Playing--The Manieren, or Grace

Notes.

Bach never wrote an oratorio in the sense of a sacred dramatic work

to be performed on a stage without action. We have shown that the

Passion settings are a portion of the Lutheran Lenten services; and the

church cantatas take much the same place as the anthem in the English

Cathedral service, with the difference of greater length, orchestral

accompaniment, and an opportunity for the congregation to take part in

the final chorale.

[Sidenote: _Christmas Oratorio_]

The so-called _Christmas Oratorio_, dated 1734, is nothing more than a

series of six cantatas, to be sung during the service on six successive

days at Christmas time. Each begins with a chorus which is followed by

several arias and recitatives, and each ends with a chorale, besides

which, chorales are also interspersed in the body of the work. The

second cantata opens with a most exquisite symphony, of a pastoral

nature something akin to the pastoral symphony in the “Messiah,” but

longer, and with the most subtle orchestral effects; especially are the

passages for two oboes interchanging with the strings most beautiful;

and the chief “motive” of the symphony recurs in the accompaniment of

the closing chorale. The character of the choruses is for the most part

one of triumphant joyfulness, and the arias have all the tender effects

which Bach so well knew how to produce.

[Sidenote: _Easter Oratorio_]

The _Easter Oratorio_ is a short cantata without a chorale.

The motets are compositions in several movements for unaccompanied

voices, from three to eight in number. The movements are interspersed

with chorales harmonised in four parts. The seventh motet, “Ich

lasse dich nicht,” though as fine as any, is considered to be almost

certainly not by Bach, and is therefore only given as an appendix in

vol. 39 of the Bach Gesellschaft edition. The appendix also gives a

figured bass and instrumental accompaniment to No. 2. “Der Geist hilft

unsrer Schwachheit auf.”

Motets by Bach and other composers are sung in the Thomas Church at

Leipsic, and in the Kreuz-Church at Dresden at vespers on Saturday

afternoons.

[Sidenote: _Secular Works_]

Bach also wrote a few secular vocal works. Among these are several

birthday, wedding and funeral cantatas--odes for important personages;

some “Dramme per Musica,” two of which, the “Choice of Hercules,” and

“Tönet ihr Pauken” are taken bodily from the _Christmas Oratorio_,

other words being adapted to the music; a cantata for the dedication

of a new organ at Störmthal, a comic cantata in praise of coffee. Some

of the secular cantatas were composed for the Concert Society which

met once a week about 1736 in a coffee-house in the Katharinen-strasse

at Leipsic, and of which Bach was the director. Among these was “The

strife between Phœbus and Pan.”

[Sidenote: _Smaller Masses and Magnificat_]

Besides the B minor Mass Bach wrote four “short” masses of much

smaller calibre, four “Sanctus,” and a “Magnificat” in D major of great

power and beauty. This work appears in two forms, of which one is much

finer than the other, and is therefore considered to be the latest. It

was the custom to intersperse the singing of the Latin Magnificat with

four chorales, but this custom not coinciding with Bach’s sense of the

fitness of things, he added the chorales as an appendix to his score.

The work is for a five part choir, with arias, a duet, and a trio.

The trio is a remarkable canon, or rather piece of canonic imitation

in the voice parts, to the words “suscepit Israel puerum suum,” to

which the strings play an accompaniment, while the oboes play in their

highest register the chorale “meine Seel’ erhebt den Herren” (“my

soul doth magnify the Lord”). And, as showing Bach’s sense of form,

the whole work is welded together by a fresh working of the material

of the opening chorus, at the words “sicut erat in principio et

nunc.... Amen.” We have remarked on this kind of construction in the

second cantata of the _Christmas Oratorio_,[75] and it is not at all

infrequent with Bach.

Except opera and oratorio Bach wrote every kind of work that was

known in his day. The Bach Gesellschaft completed the publication of

his works in full score in 1898 in some sixty large quarto volumes.

Complete editions of the vocal works in pianoforte score and the

instrumental in full score have been published by Peters, and by

Breitkopf and Härtel of Leipsic, while the editions of selected

portions published from time to time since the beginning of the

nineteenth century are innumerable.

But when we say “complete edition” it must be understood as referring

only to the works that have been preserved, for a large number seem to

have been lost when the great man died: before his property was valued

for probate there was an unseemly scramble for his manuscripts among

his elder sons.

[Sidenote: _The “year courses”_]

Mizler, in his “Necrology,” tells us the bare fact that there were five

“year courses” of cantatas, _i.e._ sets of cantatas for each Sunday

and holy day throughout the year. The Lutheran ecclesiastical year

contains fifty-nine such days (six Sundays in Lent and three in Advent

are excluded). The five courses would therefore require no less than

295 cantatas. Of these W. Friedemann took three “year courses,” since

he could use them in his post of organist at Halle, but his wretched

circumstances forced him afterwards to part with them one by one.

Forkel only knew of “eight to ten motets for double chorus,” and

twenty-one church cantatas, two five-voice masses, a mass for two

choirs, of which the first choir is accompanied by strings, the second

by wind, a double-chorus Passion with text by Picander (this must be

the “Matthew Passion”), a Sanctus, some motets, a single fugue for four

voices, and a comic cantata.

The other two “year courses,” which included about ninety cantatas, and

the two known Passions, went to C. P. Emmanuel Bach.

[Sidenote: MSS. of Works]

The MSS. of the larger number of the existing works of Bach are in the

Royal Library and in that of the Joachimsthal at Berlin. Many of these

are in autograph. The parts are of more value than the scores, since

they are not only more carefully copied, but contain the corrections

for performance.

Bach used to wrap up his scores and parts in covers on which the name

of the work and title of the composer were fully given, while on the

MSS. themselves nothing was given. If the cover were lost, therefore,

the composer’s name was lost. Many works by other composers are found

in Bach’s handwriting, both score and parts.

[Sidenote: _Difficulties in the way of publication_]

The Bach Gesellschaft has been at immense pains to search for all that

exists of Bach’s compositions. In vol. vi. they give a long account of

the difficulties they had to contend with in publishing the B minor

Mass; the owner of the autograph score, placing every difficulty in

their way, would neither sell it nor lend it to them, and finally tried

to dispose of it secretly to some unknown person. They were obliged,

therefore, to publish it from such copies as they could collect; but

almost immediately after they had done so they obtained access to the

precious MS. and were able to publish an appendix, giving whatever

variations from their own edition were found there.

Of Bach’s instrumental compositions the most important are, as we have

indicated, those for the organ and other keyed instruments. He has left

many orchestral works, but these have not the significance of his organ

and clavier music, for the symphony, in the modern sense, was not yet

developed.

[Sidenote: _Bach’s playing_]

His playing is thus described by the poet Schubart:--“J. S. Bach was

a genius of the highest order, his soul is so peculiar, so gigantic,

that centuries will have to pass before he is reached by anyone. He

played the clavier, the flügel, the cymbal with equal creative power,

and the organ--who is like him? who will ever equal him? His fist was

gigantic; he could, for example, stretch a 12th with the left hand, and

perform running passages between with the three inner fingers; he made

pedal runs with the greatest possible exactness, he drew the stops so

silently that the hearer almost sank under the magic effect; his hand

was never weary, and lasted out through a whole day’s organ playing.

“The comic style was just as familiar to him as the earnest; he was

equally a virtuoso and composer. What Newton was as a philosopher Bach

was as a musician. He had such a wealth of ideas, that no one except

his own great son can come near him; and with all this he combined also

the rarest talent for teaching.”

[Sidenote: _The Grace notes_]

With respect to the Manieren or grace-notes attacked in the “Kritische

Musikus” by Scheibe, a friend of Bach’s answered the attack by saying

that by means of these signs no performer would now be able to destroy

the effect of a piece by applying his own method; those who went wrong

would be put in the right way, and the honour of the master would be

retained.

The four chief ornaments are--

The Vorschlag (appoggiatura)

[Music: Appoggiatura Written Played]

It appears more in the parts than in the scores, and seems to have been

mostly added after they were written out. When Bach required it to be

played slowly he wrote out its exact value in full-sized notes.

The Trill (_tr._) seems to have been put down rather recklessly,

perhaps on account of fashion. Thus, the oboe sometimes has trills

given it which are quite impossible to perform.

Each composer had his own method of writing the various signs and there

was of course hopeless confusion. There is no doubt that the trill was

used to mean three different things, at the choice of the performer:

namely, the vibrato of the violin and tremulant of the organ, or a real

trill, or simply a _tenuto_. The sign [Music] appears to be equivalent

to _tenuto_, thus [Music]

Notes which are neither detached (gestossen) nor slurred, nor held

out, must be sustained for half their value, but if the word _ten._

appears above them they must be given their full value. These notes are

generally quavers and crotchets in moderate and slow tempo, and they

must not be played weakly, but with a refined and quite gentle touch.

Some of the signs can be interpreted by the fact that they are written

out in full in the parts. In this way Reitz has shown the Schleifer

(Glide) [Music: crotchet with glide] to mean [Music: crotchet preceded

by two ascending demisemiquavers] It was called in French _Coulé_,

sometimes written [Music] The Pralltriller or half trill [Music] is

lengthened when over long notes. It means no precise number of notes.

This is J. S. Bach’s own explanation,

[Music]

It will be seen that all four signs mean the same thing, and no turn

is to be played as in the shake. According to C. P. Emmanuel Bach it

must be so rapid that one does not perceive any loss of time from the

principal note.[76]

The Mordent [Music: crotchet with mordent] is to be played [Music: two

demisemiquavers descending, then dotted quaver on the initial note]

the lower note being either a semitone, as above, or a tone, as in the

little E minor fugue (Peters, 242).
