It seems that only a relatively small part of Bach's orchestral ceuvre
has been preserved for posterity. Much has been speculated about the
reasons for the above-average losses in this particular field, but up till now
no really conclusive reasons have been found. The fact that so few works for
instrumental ensemble have survived particularly from the Weimar and Cothen
periods, during which the composer directed so many excellent ensembles, has
led many researchers to the hypothesis that Bach was obliged to leave the
majority of his compositions in these places when he moved on to another post -
a common custom for which much evidence can be found in many eighteenth century
documents; other considerations establish a connection with the distribution of
Bach's compositions to his heirs after his death. Whatever the case, only one
thing is certain: that at the latest with Bach's death a veil of oblivion began
to sink over his orchestral works - partly caused also by a profound change in
taste which began in the middle of the eighteenth century. Thus great effort
was necessary in the course of the Bach renaissance at the beginning of the
nineteenth century to win back these works, which by then were completely
unknown even to Bach connoisseurs, into the performance repertoire.
Today Bach's orchestral works enjoy an enduring popularity once more.
Intensive study of this repertoire, which in spite of the regrettable gaps is
in many ways incomparable, has led to the realization that only a part of the
works can be regarded as original compositions, whereas many of the concertos
in the form in which they are known today represent transcriptions of pieces
written earlier. Among the works of the first-named category are the Brandenburg
Concertos and the three Violin Concertos, among the transcriptions
are all the concertos for one to three harpsichords, which are presumed to be
based on lost works for various melody instruments. The Concerto for four
harpsichords, BWV 1065 is a special case in that Bach did not take one of
his own works as a basis but, exceptionally, a work by Antonio Vivaldi.
Comparative studies on Bach's technique of rearranging works have led again and
again to speculations about the possible form and structure of the lost works
on which the arrangements are based, and as a consequence to attempts at
reconstruction which have resulted in pieces which are stylistically convincing
and which have proved their worth in practice; within the context of this
recording these works are intended to help fill the gaps mentioned above.
The present complete recording of Bach's orchestral works illustrates
graphically the enormous musical variety and compositional quality of this
sphere of his creative work. We meet the composer for the first time around
1715 on his first pinnacle of mastery (Brandenburg Concerto No. 5) and
accompany him for approximately a quarter of a century up to the sublime works
of his maturity - the Overture BWV 1067 and the Triple Concerto BWV
1044.
The origin and
development of the solo concerto is closely tied in with the creative work of
Italian composers such as Giuseppe Torelli, Tomaso Albinoni and above all
Antonio Vivaldi. These composers and their works were taken up eagerly by
German composers from about the second decade of the eighteenth century, but
soon underwent modifications corresponding to German traditions and styles of
composition.
In addition to solo
concertos for one instrument and accompaniment the special form of the ensemble
concerto with various instruments or groups of instruments was nurtured
particularly in Germany. The use of various tone-colours for purposes of
contrast and variation also altered the hierarchy between tutti and solo which
was for the most part also clearly established in Italian concertos in favour
of a more flexible and differentiated treatment of these formal set pieces.
This more individual approach led in Bach's case, particularly in the Brandenburg
Concertos, to a realisation of the concerto form which was in every case
convincing, novel and unrepeatable. This can already be seen in the simple fact
that each concerto is scored for a different group of instruments and
experiments with the constantly altered conditions of sound in an original way.
Brandenburg
Concerto No. 4 in G major BWV
1049 is scored for a concertino consisting of a violin and two
recorders. The consequence of this for Bach was that the violin could be used
not only as a virtuoso solo instrument above the accompaniment of the tutti strings,
but also as a continuo instrument for the two recorders. Particularly in the
first two movements of this concerto the playful changing-around of formal and
thematic hierarchies of the concerto form can be detected. In the last movement
Bach concentrates his forces in order to achieve a bold compositional tour
de force - the seamless amalgamation of fugue and concerto form. The ritornellos
of this movement thus become fugal expositions, the solos become episodes
with thematic connections.
Brandenburg
Concerto No. 5 in D major BWV
1050 may well be the first piano concerto in musical history. The virtuoso
soloist is here supported by a small concertino consisting of flute and
violin which displays an astonishing autonomy from the motivic-thematic point
of view. The imposing harpsichord cadenza which almost bursts the boundaries of
the movement was added by Bach while he was preparing the definitive score for
the dedicatee - presumably in order to remind the Margrave of his own skill as
a virtuoso. After the slow movement, an intensively worked-out quartet setting,
the work concludes with a cheerful Gigue, which, like the finale of
the fourth concerto, is in fugal form - although in a looser formal structure.
The Concerto in
F major BWV 1057 for harpsichord and two recorders represents Bach's own
transcription of his Brandenburg Concerto No. 4. In this transcription,
which was written around 1738/39, at the same time as the other harpsichord
concertos, Bach left the string passages for the most part unchanged and also
retained the two recorders which characterize the sound quality of the original
version. In contrast he transcribed the virtuoso part of the solo violin for
the harpsichord, and in doing so took particular care to re-write the idiomatic
violin figurations to make them suitable for the new instrument.
In his transcription
Bach retained the finely graded interrelations between the various instruments
(not only within the trio of soloists but also between concertino and ripieno),
extending the trio sections to a four-part texture by means of a newly
composed additional part.
The Concerto for
flute, violin and harpsichord in A minor BWV 1044, the so-called Triple
Concerto, occupies a special position within Bach's concerto ceuvre. As
far as its instrumentation is concerned the Brandenburg Concerto No. 5 can
be regarded as a companion work, but the history of its composition, its gloomy
and elegiac character and its extraordinary intensity make it unique; it can be
regarded as Bach's most unusual contribution to the concerto genre as a whole.
By reason of its mature style it is probable that the work was composed in the
1740s.
As is the case with
the other concertos with harpsichord obbligato, the Triple Concerto is
based on works of which some were written quite a long time before; unlike the F
major Concerto, however, this is not the transcription of a violin or wind
concerto from the Cothen period, but the radical re-writing of pieces for solo
harpsichord or organ. The outer movements of the work are based on a Prelude
and Fugue (BWV 894) written not later than 1714, whereas the middle
movement is an arrangement of the second movement of the Trio Sonata for
organ, BWV 527. Unlike the other concerto transcriptions, in which only the
relevant solo parts had to be adapted to the new medium, the material of the
prelude and fugue was here adapted for the solo sections of the harpsichord, to
which Bach then composed new additional parts for the two other solo
instruments as well as all the orchestral parts. He ingeniously extended the
original trio structure of the charming middle movement to a quartet which -
with an exchange of parts in the repeats - is performed by the soloists alone.
With this concerto Bach succeeded in creating a coherent whole, the
ingeniousness and remarkable originality of which convincingly refute the
various doubts expressed about its authenticity.
