The Concerto for Two Violins in D minor, BWV 1043, also known as the Double Violin Concerto, is a violin concerto of the Late Baroque era, which Johann Sebastian Bach composed around 1730. It is one of the composer's most successful works.

The Brandenburg Concertos (BWV 1046–1051) by Johann Sebastian Bach are a collection of six instrumental works presented by Bach to Christian Ludwig, Margrave of Brandenburg-Schwedt, in 1721 (though probably composed earlier). The original French title is Six Concerts avec plusieurs instruments, meaning "Six Concertos for several instruments". Some of the pieces feature several solo instruments in combination. They are widely regarded as some of the greatest orchestral compositions of the Baroque era.

The keyboard concertos, BWV 1052–1065, are concertos for harpsichord (or organ), strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065). Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and Brandenburg Concerto No. 5 in D major, with the same scoring. In addition, there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo. Most of Bach's harpsichord concertos (with the exception of the 5th Brandenburg Concerto) are thought to be arrangements made from earlier concertos for melodic instruments probably written in Köthen. In many cases, only the harpsichord version has survived. They are among the first concertos for keyboard instrument ever written.

The concerto for two harpsichords in C minor, BWV 1060, is a concerto for two harpsichords and string orchestra by Johann Sebastian Bach. It is likely to have originated in the second half of the 1730s as an arrangement of an earlier concerto, also in C minor, for oboe and violin. That conjectural original version of the concerto, which may have been composed in Bach's Köthen years (1717–1723), is lost, but has been reconstructed in several versions known as BWV 1060R.

The Concerto for Two Violins in D minor, BWV 1043, also known as the Double Violin Concerto, is a violin concerto of the Late Baroque era, which Johann Sebastian Bach composed around 1730. It is one of the composer's most successful works.

The organ concertos of Johann Sebastian Bach are solo works for organ, transcribed and reworked from instrumental concertos originally composed by Antonio Vivaldi and the musically talented Prince Johann Ernst of Saxe-Weimar. While there is no doubt about the authenticity of BWV 592–596, the sixth concerto BWV 597 is now probably considered to be spurious. Composed during Bach's second period at the court in Weimar (1708–1717), the concertos can be dated more precisely to 1713–1714. Bach also made several transcriptions of Vivaldi's concertos for single, two and four harpsichords from exactly the same period in Weimar. The original concertos were picked from Vivaldi's Op.3, L'estro armonico, composed in 1711, a set of twelve concertos for one, two and four violins. The publication of these Bach transcriptions by C.F. Peters in the 1850s and Breitkopf & Härtel in the 1890s played a decisive role in the Vivaldi revival of the twentieth century. There are six organ concertos:

The Bach-Werke-Verzeichnis (German: [ˈbax ˌvɛʁkə fɐˈtsaɪçnɪs], lit. 'Bach Works Catalogue'; BWV) is a catalogue of compositions by Johann Sebastian Bach. It was first published in 1950, edited by Wolfgang Schmieder. The catalogue's second edition appeared in 1990 and the third edition in 2022. The catalogue groups compositions by genre. Even within a genre, compositions are not necessarily collated chronologically. In part this reflects the fact that some compositions cannot be dated. However, an approximate or precise date can be assigned to others: for example, BWV 992 was composed many years before BWV 1.

The keyboard concertos, BWV 1052–1065, are concertos for harpsichord (or organ), strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065).

Johann Sebastian Bach's vocal music includes cantatas, motets, masses, Magnificats, Passions, oratorios, four-part chorales, songs and arias. His instrumental music includes concertos, suites, sonatas, fugues, and other works for organ, harpsichord, lute, violin, viola da gamba, cello, flute, chamber ensemble, and orchestra. There are over 1,000 known compositions by Bach. Almost all are listed in the Bach-Werke-Verzeichnis (BWV), which is the best known and most widely used catalogue of Bach's compositions.

The Harpsichord Concerto in D minor, BWV 1052, is a concerto for harpsichord with two violin parts, viola and basso continuo by Johann Sebastian Bach. In three movements, marked Allegro, Adagio and Allegro, it is the first Bach listed in his manuscript of Bach's harpsichord concertos, BWV 1052–1065.

The concerto for two harpsichords in C minor, BWV 1060, is a concerto for two harpsichords and string orchestra by Johann Sebastian Bach. It is likely to have originated in the second half of the 1730s as an arrangement of an earlier concerto, also in C minor, for oboe and violin.

Johann Sebastian Bach's Violin Concertos, BWV 1041–1043, and his six Brandenburg Concertos survive in their original instrumentation. His harpsichord concertos are mostly adaptations of concertos originally written for other solo instruments. In his early career Bach transcribed concertos by other composers for solo organ (BWV 592–596) and for solo harpsichord (BWV 972–987). Bach's Italian Concerto, composed in 1735, was one of his few works that he published during his life-time: it is an example of an unaccompanied concerto for two-manual harpsichord.

The oboe d'amore (Italian for 'love oboe'; (pronounced [ˈɔːboe daˈmoːre]), less commonly hautbois d'amour (French: [obwɑ damuʁ]), is a double reed woodwind musical instrument in the oboe family. Slightly larger than the oboe, it has a less assertive and a more tranquil and serene tone, and is considered sometimes considered the alto of the oboe family, between the oboe (soprano) and the cor anglais, or English horn (tenor, but sometimes also considered an alto). It is a transposing instrument pitched in A sounding a minor third lower than it is notated. The bell (called Liebesfuß) is pear-shaped and the instrument uses a crook or bocal, similar to but shorter than that of the cor anglais.

The four orchestral suites BWV 1066–1069 (called ouvertures by their composer) are four suites by Johann Sebastian Bach from the years 1724–1731. The name ouverture refers only in part to the opening movement in the style of the French overture, in which a majestic opening section in relatively slow dotted-note rhythm in duple meter is followed by a fast fugal section, then rounded off with a short recapitulation of the opening music. More broadly, the term was used in Baroque Germany for a suite of dance-pieces in French Baroque style preceded by such an ouverture. This genre was extremely popular in Germany during Bach's day, and he showed far less interest in it than was usual: Robin Stowell writes that "Telemann's 135 surviving examples [represent] only a fraction of those he is known to have written"; Christoph Graupner left 85; and Johann Friedrich Fasch left almost 100. Bach did write several other ouverture (suites) for solo instruments, notably the Cello Suite no. 5, BWV 1011, which also exists in the autograph Lute Suite in G minor, BWV 995, the Keyboard Partita no. 4 in D, BWV 828, and the Overture in the French style, BWV 831 for keyboard. The two keyboard works are among the few Bach published, and he prepared the lute suite for a "Monsieur Schouster", presumably for a fee, so all three may attest to the form's popularity. Scholars believe that Bach did not conceive of the four orchestral suites as a set (in the way he conceived of the Brandenburg Concertos), since the sources are various, as detailed below. The Bach-Werke-Verzeichnis catalogue includes a fifth suite, BWV 1070 in G minor. However, this work is highly unlikely to have been composed by J. S. Bach. Gustav Mahler arranged portions of BWV 1067 and 1068 for orchestra, harpsichord, and organ. They were played several times during Mahler's first tour of the New York Philharmonic, with Mahler on harpsichord and Harry Jepson on organ. The Italian composer Giuseppe Martucci (1856–1909) also prepared transcriptions of three of the suites (BWV 1066, 1067, and 1068) for solo piano.

In addition, there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo. Most of Bach's harpsichord concertos (with the exception of the 5th Brandenburg Concerto) are thought to be arrangements made from earlier concertos for melodic instruments probably written in Köthen. In many cases, only the harpsichord version has survived. They are among the first concertos for keyboard instrument ever written.

E-flat major is a major scale based on E♭, consisting of the pitches E♭, F, G, A♭, B♭, C, and D. Its key signature has three flats. Its relative minor is C minor, and its parallel minor is E♭ minor, (or enharmonically D♯ minor). The E♭ major scale is: The E-flat harmonic major and melodic major scales are

The Violin Concerto in A minor, BWV 1041, is a violin concerto by Johann Sebastian Bach. It shows the influence of Italian composers such as Bach's older contemporary Vivaldi. Bach is known to have studied Vivaldi's music from around 1714 when he was working at Weimar. Italian influence can be seen in keyboard music he composed around that time. However, the date of the concerto is the subject of dispute as the original score has not survived. It could have been written at any of three locations: Weimar. Most scholars think it was written after Bach left Weimar in 1717 (the violinist Lina Tur Bonet, who suggests it was written there, adheres to the minority position). Köthen. It is "generally thought to have been composed at Köthen". Bach worked at the court there in the period 1717–23 and his duties included directing a small orchestra. Leipzig. It could have been written at Leipzig, as the only autograph source to survive is a set of parts Bach copied out (along with Carl Philipp Emanuel Bach, Johann Ludwig Krebs, and an unknown copyist) in Leipzig c. 1730 from a now lost score or draft. Christoph Wolff has argued that the work may have been written during Bach's time as director of Leipzig's Collegium Musicum. John Butt takes a similar view, suggesting that Bach wrote it "probably soon after taking over the Leipzig Collegium Musicum in 1729".

The Violin Concerto in E major, BWV 1042, is a violin concerto by Johann Sebastian Bach. It is based on the three-movement Venetian concerto model, albeit with a few unusual features; each movement has "un-Italian characteristics". The piece has three movements: While there are two 18th-century scores, neither is autographed; however, Bach re-used the concerto as the model for his Harpsichord Concerto in D major, BWV 1054, found in his 1737–39 autographed manuscript of these works. The concerto is thought to have been written when Bach was working for the court of Köthen or when Bach was in Leipzig.
