Bachs seks Brandenburgkonserter
Det finnes neppe noen bedre vei inn i barokkmusikkens vidunderlige verden enn gjennom å oppleve Johann Sebastian Bachs Brandenburgkonserter, enten man lar seg henføre av melodiene, kjenne det rykke i hoftene av det rytmiske drivet eller la seg bergta av Bachs harmoniske oppfinnsomhet.
I forbindelse med Barokkanernes konserter i Oslo og Moss med utvalgte Brandenburgkonserter, ble det et møte og en samtale med Johan Nicolai Mohn - musiker og sjef for ensemblet - om Bach, Barokkanerne og Brandenburgkonsertene. Barokkanerne er et ensemble i verdensklasse. med internasjonale musikere, solister og ledere.

Gjennom musikkhistorien er det blant sjeldenhetene at slik musikk oppstår, og Bachs Brandenburgkonserter har på mange måter aldri blitt overgått i kompleksitet, skjønnhet, variasjon og unike formspråk.
Brandenburgerkonsertene, eller Six Concerts à plusieurs instruments, er en samling av seks concerti grossi, komponert av Johann Sebastian Bach i tidsrommet 1711-1720. Konsertene er blant de mest spilte orkesterverkene fra barokken.
Konsertene ble i 1721 tilegnet prins Christian Ludwig, da han ble kronet markgreve av Brandenburg. Bach sendte konsertene som en slags portefølje til markgreven, i det han var i ferd med å søke seg vekk fra kapellmesterstillingen sin i Köthen. Bach lyktes ikke med å oppnå en post ved hoffet til markgreven, og senere ble notemanuskriptet liggende bortglemt i Brandenburgs statsarkiver i vel hundre år, før mesterverkene ble gjenoppdaget i 1849. Takket være verkenes originalitet og kunstneriske kvalitet er Brandenburgerkonsertene blant de mest gjenkjennelige og oftest spilte orkesterverkene fra barokken. Konsertene er ikke bare en storartet fremvisning av Bachs tekniske dyktighet, men de skiller seg ut med en uvanlig kreativ og fargerik instrumentasjon.

Brandenburgkonsert No. 1 i F-dur, BWV 1046
Ars Lyrica Houston
The Brandenburg Concerto No. 1, BWV 1046.2 (BWV 1046), is the only one in the collection with four movements. The concerto also exists in an alternative version, Sinfonia BWV 1046.1 (formerly BWV 1046a), which appears to have been composed during Bach's years at Weimar. The Sinfonia, which lacks the third movement entirely, and the Polacca (or Poloinesse, polonaise) from the final movement, appears to have been intended as the opening of the cantata Was mir behagt, ist nur die muntre Jagd, BWV 208. This implies a date of composition possibly as early as the 1713 premiere of the cantata, although it could have been used for a subsequent revival.
The first movement can also be found as the sinfonia of a later cantata Falsche Welt, dir trau ich nicht, BWV 52, but in a version without the piccolo violin that is closer to Sinfonia BWV 1046a. The third movement was used as the opening chorus of the cantata Vereinigte Zwietracht der wechselnden Saiten, BWV 207, where the horns are replaced by trumpets.
Brandenburgkonsert No. 2 i F-dur, BWV 1047
The trumpet part is still considered one of the most difficult in the entire repertoire, and was originally written for a clarino specialist, almost certainly the court trumpeter in Köthen, Johann Ludwig Schreiber. After clarino skills were lost in the eighteenth century and before the rise of the historically informed performance movement of the late twentieth century, the part was usually played on the valved trumpet, and sometimes on a modern F trumpet, a French horn, or even a B♭ piccolo trumpet.
The clarino does not play in the second movement, as is common practice in baroque era concerti. This is due to its construction, which allows it to play only in major keys. Because concerti often move to a minor key in the second movement, concerti that include the instrument in their first movement and are from the period before the valved trumpet was commonly used usually exclude the trumpet from the second movement.
The first movement of this concerto was chosen as the first musical piece to be played on the Voyager Golden Record, a phonograph record containing a broad sample of Earth's common sounds, languages, and music sent into outer space with the two Voyager probes. The first movement served as a theme for Great Performances in the early-to-mid 1980s, while the third movement served as the theme for William F. Buckley Jr.'s Firing Line; a revival featuring Margaret Hoover would also use the first movement.
Brandenburgkonsert No. 3 i G-dur, BWV 1048
The second movement consists of a single measure with the two chords that make up a 'Phrygian half cadence' and-although there is no direct evidence to support it-it was likely that these chords are meant to surround or follow a cadenza improvised by a harpsichord or violin player. Modern performance approaches range from simply playing the cadence with minimal ornamentation (treating it as a sort of "musical semicolon"), to inserting movements from other works, to cadenzas varying in length from under a minute to over two minutes. Wendy Carlos's three electronic performances (from Switched-On Bach, Switched-On Brandenburgs, and Switched-On Bach 2000) have second movements that are completely different from each other. Occasionally, the third movement from Bach's Sonata for Violin and Continuo in G, BWV 1021 (marked Largo) is substituted for the second movement as it contains an identical 'Phrygian cadence' as the closing chords. The Largo from the Sonata for Violin and Obbligato Harpsichord in G major, BWV 1019, has also been used.
The outer movements use the ritornello form found in many instrumental and vocal works of the time. The first movement can also be found in reworked form as the sinfonia of the cantata Ich liebe den Höchsten von ganzem Gemüte, BWV 174, with the addition of three oboes and two horns.
This concerto is the shortest of the six.
Brandenburgkonsert No. 4 i G-dur, BWV 1049
Netherlands Bach Society
The violin part in this concerto is extremely virtuosic in the first and third movements. In the second movement, the violin provides a bass when the concertino group plays unaccompanied.
It has been debated what instrument Bach had in mind for the "fiauti d'echo" parts. Nowadays these are usually played on alto recorders, although traverse flutes are sometimes used instead: it is also theorized Bach's original intent may have been the flageolet. In some performances, such as those conducted by Nikolaus Harnoncourt, the two recorders are positioned offstage, thus giving an "echo" effect.
Bach adapted the 4th Brandenburg concerto as a harpsichord concerto, BWV 1057.
Brandenburgkonsert No. 5 i D-dur, BWV 1050
The harpsichord is both a concertino and a ripieno instrument. In the concertino passages the part is obbligato; in the ripieno passages it has a figured bass part and plays continuo.
This concerto makes use of a popular chamber music ensemble of the time (flute, violin, and harpsichord), which Bach used on its own for the middle movement. It is believed[by whom?] that it was written in 1719, to show off a new harpsichord by Michael Mietke which Bach had brought back from Berlin for the Köthen court. It is also thought that Bach wrote it for a competition at Dresden with the French composer and organist Louis Marchand; in the central movement, Bach uses one of Marchand's themes. Marchand fled before the competition could take place, apparently scared off in the face of Bach's great reputation for virtuosity and improvisation.
The concerto is well suited throughout to showing off the qualities of a fine harpsichord and the virtuosity of its player, but especially in the lengthy solo cadenza to the first movement. It seems almost certain that Bach, considered a great organ and harpsichord virtuoso, was the harpsichord soloist at the premiere. Scholars have seen in this work the origins of the solo keyboard concerto as it is the first example of a concerto with a solo keyboard part.
Brandenburgkonsert No. 6 i B-dur, BWV 1051

The absence of violins is unusual. Viola da braccio means the normal viola, and is used here to distinguish it from the viola da gamba. When the work was written in 1721, the viola da gamba was already an old-fashioned instrument: the strong supposition that one viola da gamba part was taken by his employer, Prince Leopold, also points to a likely reason for the concerto's composition-Leopold wished to join his Kapellmeister playing music. Other theories speculate that, since the viola da braccio was typically played by a lower socioeconomic class (servants, for example), the work sought to upend the musical status quo by giving an important role to a "lesser" instrument. This is supported by the knowledge that Bach wished to end his tenure under Prince Leopold. By upsetting the balance of the musical roles, he would be released from his servitude as Kapellmeister and allowed to seek employment elsewhere.
The two violas start the first movement with a vigorous subject in close canon, and as the movement progresses, the other instruments are gradually drawn into the seemingly uninterrupted steady flow of melodic invention which shows the composer's mastery of polyphony. The two violas da gamba are silent in the second movement, leaving the texture of a trio sonata for two violas and continuo, although the cello has a decorated version of the continuo bass line. In the last movement, the spirit of the gigue underlies everything, as it did in the finale of the fifth concerto.
