Violin concerto

A violin concerto is a concerto for solo violin (occasionally, two or more violins) and instrumental ensemble, customarily orchestra. Such works have been written since the Baroque period, when the solo concerto form was first developed, up through the present day. Many major composers have contributed to the violin concerto repertoire, with the best known works including those by Bach, Bartók, Beethoven, Brahms, Bruch, Mendelssohn, Mozart, Paganini, Prokofiev, Shostakovich, Sibelius, Tchaikovsky, and Vivaldi. Traditionally a three-movement work, the violin concerto has been structured in four movements by a number of modern composers, including Dmitri Shostakovich, Igor Stravinsky, and Alban Berg (in the latter, the first two and last two movements are connected, with the only break coming between the second and third). In some violin concertos, especially from the Baroque and modern eras, the violin (or group of violins) is accompanied by a chamber ensemble rather than an orchestra—for instance, Vivaldi's L'estro armonico, originally scored for four violins, two violas, cello, and continuo, and Allan Pettersson's first concerto, for violin and string quartet.

Concerto

A concerto (from the Italian: concerto, plural concerti or, often, the anglicised form concertos) is a musical composition, whose characteristics have changed over time. In the 17th century, "sacred works for voices and orchestra were typically called concertos." J. S. Bach "was thus reflecting a long-standing tradition when he used the title `concerto' for many of the works that we know as cantatas.". But in recent centuries, up to the present, a concerto is a piece usually composed in three parts or movements, in which (usually) one solo instrument (for instance, a piano, violin, cello or flute) is accompanied by an orchestra or concert band.

The etymology is uncertain, but the word seems to have originated from the conjunction of the two Latin words conserere (meaning to tie, to join, to weave) and certamen (competition, fight): the idea is that the two parts in a concerto, the soloist and the orchestra or concert band, alternate episodes of opposition, cooperation, and independence in the creation of the music flow.

List of compositions by Johann Sebastian Bach

There are over 1000 known compositions by Johann Sebastian Bach. Nearly all of them are listed in the Bach-Werke-Verzeichnis (BWV), which is the best known and most widely used catalogue of Bach's compositions.

Listing Bach's compositions

The earliest lists of Bach's compositions are given by his biographers, starting from his obituary which gives a list of instrumental works printed during the composer's lifetime (from Clavier-Übung I to The Art of Fugue), followed by a list which groups other types of compositions he wrote. The first separately published biography of the composer, by Johann Nikolaus Forkel, follows the same setup: its ninth chapter first lists printed works (adding four-part chorales that were published in the second half of the 18th century), followed by a rough overview of the unpublished ones. In the first half of the 19th century more works were published, so the next biographies (Schauer and Hilgenfeldt in 1850) had more elaborate appendices listing printed works, referring to these works by publisher, and the number or page number given to the works in these publications. So, for example, the Prelude and Fugue in E-flat major can be indicated as "C. F. Peters Vol. III No. 1", or any of the variants ("Griepenkerl and Roitzsch Vol. 3 p. 2", "Peters Book 242 p. 2", "P. S. V., Cah. 3 (242), No. 1", etc.)

Harpsichord concerto

A harpsichord concerto is a piece of music for an orchestra with the harpsichord in a solo role (though for another sense, see below). Sometimes these works are played on the modern piano (see piano concerto). For a period in the late 18th century, Joseph Haydn and Thomas Arne wrote concertos that could be played interchangeably on harpsichord, fortepiano, and (in some cases) pipe organ.

The Baroque harpsichord concerto

The harpsichord was a common instrument, but never as popular as string or wind instruments in the concerto role, probably due to its relative lack of volume in an orchestral setting. In this context, harpsichords were more usually employed as a continuo instrument, playing a harmonised bass part in nearly all orchestral music, the player often also directing the orchestra.

Bach's Brandenburg Concerto No.5 in D major, BWV 1050, may be the first work in which the harpsichord appears as a concerto soloist. In this piece, its usual continuo role is alternated with prominent solo obbligato episodes in all three movements. In the first movement the harpsichord, after rapid scales up and down the length of its range, embarks on a solo cadenza which lasts for 3–4 minutes, while the orchestra is silent.

Brandenburg Concertos

The Brandenburg Concertos by Johann Sebastian Bach (BWV 1046–1051, original title: Six Concerts à plusieurs instruments) are a collection of six instrumental works presented by Bach to Christian Ludwig, Margrave of Brandenburg-Schwedt, in 1721 (though probably composed earlier). They are widely regarded as some of the best orchestral compositions of the Baroque era.

History

Bach wrote out the music himself for presentation to the Margrave rather than leaving it to a copyist. While he took the opportunity to revise the music, most likely, it was not freshly composed. He appears to have selected the six pieces from concertos he had composed over a number of years while Kapellmeister at Köthen, and possibly extending back to his employment at Weimar (1708–17).

Bach's dedication to the Margrave was dated 24 March 1721. Translated from the original French, the first sentence of Bach's dedication reads:

Bach's reference to his scoring the concertos for "several instruments" (Concerts avec plusieurs instruments) is an understatement. Bach used the "widest spectrum of orchestral instruments … in daring combinations," as Christoph Wolff has commented. "Every one of the six concertos set a precedent in scoring, and every one was to remain without parallel." Heinrich Besseler has noted that the overall forces required (leaving aside the first concerto, which was rewritten for a special occasion) tallies exactly with the 17 players Bach had at his disposal in Köthen.
