Brandenburg
Concerto No. 2 in F Major, BWV 1047
Although
they are often discussed, recorded, and published as a collection,
the 6 concertos encompassing the so-called Brandenburg Concertos
were not written all at once, nor for the same ensemble. Scholars
suspect that nos. 1, 3, and 6 may have been written much earlier
than the others, perhaps dating from Bach's Weimar period (1708-1717),
while 2, 4, and 5 most likely came from Cöthen. Bach later
put the 6 concertos together and dedicated them to the margrave
of Brandenburg, hoping to get a new job out of it. (He did not.)
In fact, the only commonality among the six is the use of a three-movement,
fast-slow-fast design; this indicates that the Brandenburg Concerti
were based on Italian concerto format. Beyond that, they have nothing
in common, and, in fact, among the 6, there is as much variety as
you can find in any six works by Bach.
Brandenburg
Concerto No. 2 in F major might be the most popular of the
6 for its brilliant scoring. This is an example of a common orchestral
genre of the Baroque known as the concerto
grosso. (The same is true for Brandenburg Concerto No. 5
in D major). A concerto grosso utilizes two ensembles, one
large and one small. The large one is called the ripieno
or tutti; this includes the orchestra. A group of soloists
comprise the smaller group, entitled the concertino (meaning
little concerto group). The number of soloists and instruments used
was entirely up to the composer to decide. Some composers, like
Archangelo Corelli (1653-1713), always used the same instruments
in the concertino (for Corelli, it was always two violins
and cello, plus continuo).
In
the present case, Bach's ripieno includes solo flute [originally
recorder], trumpet, violin, oboe, and continuo. (The continuo is
never omitted, as it provides the harmonic foundation of the entire
piece.) The trumpet part is very virtuosic, written to employ a
style of playing known as "clarino playing," in which
the trumpeter played in the highest range of the instrument, and
using quickly-changing lip pressure to change the pitch of the instrument.
(The trumpet of Bach's day was a long tubed instrument without valves,
which were added around 1815.) Today, we normally hear a piccolo
trumpet (sometimes called a "Bach trumpet"), which is
pitched higher to play these passages more easily; however, the
tone of the instrument is quite brilliant, and tends to dominate
the texture whenever it is played.
Brandenburg
Concerto No. 2 provides an excellent example of Bach's use
of a ritornello, which we discussed briefly in the B
minor Mass. (See discussion of the Credo).
As I mentioned there, Bach was an unofficial student of the composer
Antonio Vivaldi (1678-1741), whose works he copied by hand (the
best way to get copies of music in those days) and sometimes rescored.
One of the hallmarks of Vivaldi's style is his use of orchestral
ritornellos, not just in his concertos (as in the concerto Spring
from The Four Seasons), but sometimes in his sacred music
(as in the first movement of his famous Gloria). Vivaldi
typically began his concertos with a full statement of the orchestral
ritornello (sometimes even two full statements), then in between
solo passages, he would bring the ritornello back again, though
often each subsequent appearance was a bit shorter than the previous.
Bach probably got the idea of using a ritornello from studying Vivaldi,
and even in this piece, you'll see that some ritornello statements
are indeed shorter than the first. Here is the ritornello which
opens the Brandenburg Concerto No. 2:

Listen
to it...
What's
interesting about this concerto is not necessarily the use of a
ritornello, although that certainly is the most recognizable aspect.
What interests me is that Bach uses a second theme which he also
treats as a ritornello, that is, a recurring theme, although this
one appears exclusively in the instruments of the concertino
(the soloists):

Listen
to it...
At
the first entrance of each soloist (violin, oboe, flute, then trumpet),
each initially plays this theme, and later variations also appear.
All in all, we will hear this "solo ritornello" a total
of eight times.
There
are three points I'd like to make about these two themes.
-
These
two recurring themes make up the bulk of the melodic material
and passagework throughout this entire movement.
-
The
first theme, the so-called "orchestral ritornello,"
is played by all instruments, solo and ripieno,
at various times in the movement.
- Both
contain many notes, especially groups of rapid sixteenth-notes,
which create a perpetual motion effect, and cause one phrase to
run immediately into another. Because of these three ideas, Bach
creates an unusually tight, uniform movement, making it difficult
for the listener sometimes to distinguish between the "solo"
passages and the ripieno.
The
second movement is unusual in its scoring. Whereas in the previous
movement, we could sometimes not distinguish between the ripieno
and the concertino, in the second movement this issue is
moot. There IS NO ripieno. The second movement, an andante,
is scored for three soloists plus continuo. The bright timbre of
the trumpet is omitted to create a more intimate setting and to
provide strong contrast with the two faster movements. Further contrast
is created by Bach's choice of D minor as the key for this movement.
The movement is a minuet, a medium tempo dance in triple meter.
(3/4 is most common, which is what Bach uses here). The thematic
content is extremely tight here, even more than in the first movement,
which only contained two basic themes. In this case, everything
comes out of the first six beats of the violin line:
