Brandenburg concertos

The six Brandenburg concertos (BWV 1046–1051) by Johann Sebastian Bach are a collection of instrumental works presented by Bach to the Margrave of Brandenburg in 1721, but probably composed earlier.

History
By 1721, Bach's third year as Kapellmeister at Anhalt-Cöthen, he was becoming restless and began looking for career opportunities outside the small town. As the story commonly goes, on March 24, he assembled these six concertos (which had almost certainly been performed at Cöthen) and presented them, by way of a job application, to the Margrave Christian Ludwig of Brandenburg. (The application was not successful.)
The concertos have little in common; the dedication page Bach wrote for the collection merely indicates they are six pieces for several instruments. Indeed, the six works seem to reflect an effort by the composer to write for as many different ensembles as possible.
The concertos: orchestral versus chamber music
In modern times these works have been performed by chamber orchestras, using a fairly substantial string section. However, they have also been performed as chamber music, with just one instrument on each part. The very small size of the orchestra in Bach's day means that the distinction between the two approaches would not have been very significant at that time.
A minor detail about the Fifth Concerto indicates something about the size of the ensembles with which they were originally performed. This concerto (see below) features a harpsichord solo, which was almost certainly performed by Bach himself. It also lacks a second violin part. The best explanation of this goes as follows: We know that when playing in the string section, Bach preferred to take the viola part; according to a surviving letter, this was so he could sit "in the middle of the harmony." Since as keyboard soloist Bach was not available to take the viola part for this concerto, one of his violinists must have had to move over to play the viola. The explanation, of course, relies on the assumption that Bach's ensemble used only one musician per part.
What we will probably never know is whether, had Bach worked in a wealthier musical establishment, he would have wanted to assign more musicians to the string section. This remains a choice that modern performers are free to make.
The individual concertos
Brandenburg Concerto #1 in F major
- I. (Allegro)
- II. Adagio
- III. Allegro
- IV. Menuetto; Trio I; Polacca; Trio II
The First Concerto in F major calls for two French horns, three oboes, a bassoon, and a violino piccolo as well as two violins, a viola, and a basso continuo for accompaniment. This concerto is the only one in the collection of six with four movements, rather than three. The last movement is an extensive and relaxed sequence, consisting of a minuet played four times, with a separate trio or polacca section for each of the intervals. An earlier version of this concerto survives as a sinfonia, BWV 1046a.
Brandenburg Concerto #2 in F major
- I. (Allegro)
- II. Andante
- III. Allegro assai
This is in the form of a concerto grosso, and calls for a somewhat simpler but rather unusual ensemble of trumpet, recorder, oboe, and solo violin, with two violins, a viola, and a basso continuo again accompanying. Scholars today continue to be astonished that the trumpeter in Bach's ensemble was able to handle the rapid passagework of this part while playing an instrument that had no valves. Even today, when a special valved piccolo trumpet is often used, the part is considered very demanding.
Brandenburg Concerto #3 in G major
- I. (Allegro)
- II. Adagio - though it is only a single measure consisting of two chords.
- III. Allegro
This concerto is often cited as the prototype of the modern string quartet as Bach here calls for only stringed instruments. The three violins, three violas, and three cellos are accompanied by a basso continuo. The second movement consists of purely the two chords that make up a Phrygian mode cadence and it was likely that these chords surrounded or followed a cadenza improvised by a keyboard or violin player.
Occasionally, the third movement from Bach's "Sonata for Violin and Continuo in G , BWV. 1021" (marked Largo) is substituted for the second movement of this Brandenburg concerti as it contains an identical Phrygian mode cadence as the closing chords.
The score of the Third Concerto is available from the Mutopia project:
- 1st and 2nd movements (http://www.mutopiaproject.org/cgibin/piece-info.cgi?id=297)
- 3rd movement (http://www.mutopiaproject.org/cgibin/piece-info.cgi?id=406)
Brandenburg Concerto #4 in G major
- I. (Allegro)
- II. Andante
- III. Presto
This concerto—for violin and two recorders accompanied by two violins, a viola, and a basso continuo—uses these common instruments in uncommon ways; the demanding solo violin part mimics the continuo accompaniment at times, moving what is traditionally foundation to the treble register. In modern performances flutes are sometimes substituted for recorders.
Brandenburg Concerto #5 in D major
- I. Allegro
- II. Affectuoso
- III. Allegro
This concerto was written for flute, violin, and harpsichord, with violin, viola, and basso continuo support. It makes use of a popular chamber music ensemble configuration (flute, violin, and harpsichord). It is believed that the concerto was written in 1719, shortly after Bach had brought back from Berlin a new harpsichord for the Cöthen ensemble. The concerto is well suited throughout to showing off the qualities of a fine harpsichord, but especially in the lengthy and flamboyant solo cadenza to the first movement. It seems almost certain that Bach, considered a great keyboard virtuoso in his day, was the keyboard soloist at the premiere. Scholars have seen in this work the origin of the virtuoso keyboard concerto, developed later in Bach's own work as well as in the piano concerti of Mozart and Beethoven.
Brandenburg Concerto #6 in B flat major
- I. (Allegro)
- II. Adagio ma non tanto
- III. Allegro
This concerto sets two trio groups against each other. On one side sit the "modern" instruments: two violas and a cello, while on the other are the "old-fashioned" violas da gamba and double bass. These opposed low-register trios present a series of call-and-response motifs.
Other
The Brandenburg concertos, especially the Second, Third, Fourth, and Fifth, continue to be very popular to this day and are frequently performed and recorded. Generally, mainstream symphony orchestras play them less often than in the past, and the works are now more often the province of authentic performance ensembles.
As with other familiar works of classical music, the Brandenburg Concertos have repeatedly been mined for use in film scores and as theme music for television programs. An excerpt of the Second Concerto was placed upon the Voyager Golden Record on the Voyager spacecraft, and the Third Concerto was used as the original theme of the BBC programme "The Antiques Roadshow".
