Posts in Johann Sebastian Bach

The terrible surgery that blinded Bach At the age of 57, Johann Sebastian Bach started to experience a number of health problems. Most serious was an affliction to his eyes, a condition that seemingly had plagued him from a young age. “His eyes had naturally bad vision, and that was further weakened by a lot of studying, sometimes even all night long, especially during his youth.” Present-day ophthalmologists, having studied a number of paintings, suggest that Bach “was probably mildly myopic.” #classicalmusic #bach #orchestra We are a educational channel specializing in history of classical music.

Johann Sebastian Bach (31 March 1685 – 28 July 1750) was a German composer and musician of the late Baroque period. He is known for his orchestral music such as the Brandenburg Concertos; instrumental compositions such as the Cello Suites; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schubler Chorales and the Toccata and Fugue in D minor; and vocal music such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach revival he has been generally regarded as one of the greatest composers in the history of Western music. The Bach family already counted several composers when Johann Sebastian was born as the last child of a city musician in Eisenach. After being orphaned at the age of 10, he lived for five years with his eldest brother Johann Christoph, after which he continued his musical education in Lüneburg. From 1703 he was back in Thuringia, working as a musician for Protestant churches in Arnstadt and Mühlhausen and, for longer stretches of time, at courts in Weimar, where he expanded his organ repertory, and Köthen, where he was mostly engaged with chamber music. From 1723 he was employed as Thomaskantor (cantor at St Thomas's) in Leipzig. There he composed music for the principal Lutheran churches of the city, and for its university's student ensemble Collegium Musicum. From 1726 he published some of his keyboard and organ music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer, a situation that was little remedied when he was granted the title of court composer by his sovereign, Augustus III, Elector of Saxony and King of Poland, in 1736. In the last decades of his life he reworked and extended many of his earlier compositions. He died of complications after eye surgery in 1750 at the age of 65. Bach enriched established German styles through his mastery of counterpoint, harmonic, and motivic organisation, and his adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include hundreds of cantatas, both sacred and secular. He composed Latin church music, Passions, oratorios, and motets. He often adopted Lutheran hymns, not only in his larger vocal works, but for instance also in his four-part chorales and his sacred songs. He wrote extensively for organ and for other keyboard instruments. He composed concertos, for instance for violin and for harpsichord, and suites, as chamber music as well as for orchestra. Many of his works employ the genres of canon and fugue. Throughout the 18th century, Bach was primarily valued as an organist, while his keyboard music, such as The Well-Tempered Clavier, was appreciated for its didactic qualities. The 19th century saw the publication of some major Bach biographies, and by the end of that century all of his known music had been printed. Dissemination of scholarship on the composer continued through periodicals (and later also websites) exclusively devoted to him, and other publications such as the Bach-Werke-Verzeichnis (BWV, a numbered catalogue of his works) and new critical editions of his compositions. His music was further popularised through a multitude of arrangements, including the Air on the G String and "Jesu, Joy of Man's Desiring", and of recordings, such as three different box sets with complete performances of the composer's oeuvre marking the 250th anniversary of his death.

Prelude and Fugue in E minor, BWV 855, is the 10th prelude and fugue for keyboard (harpsichord) in the first book of The Well Tempered Clavier, composed in 1722 by Johann Sebastian Bach. The Prelude in E minor, BWV 855a, features as No. 18 ("Praeludium 5") in the 1720 Klavierbüchlein für Wilhelm Friedemann Bach. BWV 855a may also refer to both this Prelude and a Fughetta in the same key, an early version of BWV 855. Alexander Siloti made a piano arrangement in B minor of the Prelude BWV 855a. Where the 1998 version of the Bach-Werke-Verzeichnis (BWV2a) described BWV 855a as only a Prelude, based on its appearance in the Klavierbüchlein für Wilhelm Friedemann Bach, BWV 855a may also refer to both this Prelude and a Fughetta in E minor, found in a manuscript copy made between 1750 and the early 19th century, once owned by F. Konwitschny but later lost. The Prelude and Fughetta were published in Series V, Volume 6.1 of the Neue Bach-Ausgabe, based on various sources for the Prelude, and on the Konwitschny source (of which a film copy had been preserved) for the Fughetta. BWV 855a is an early version of BWV 855, No. 10 in the 1722 first book of the Well-Tempered Clavier. This arrangement has been described as "perhaps Siloti's most tender and perfect" transcription. It transposes Bach's original down from the original E minor into B minor, with the steady sixteenth note figuration that was originally given by Bach to the left hand being instead assigned to the right hand. Siloti also adds a repeat of the entire work, in order to allow for a change of voicing where the melody in the left hand is emphasized. The chords in the left hand are arpeggiated; however according to Siloti's daughter Kyriena (to whom the work was dedicated), he would omit the arpeggiation on the first pass and restore it on the repeat in order to heighten the effect of the left-hand melody. It has been performed by many pianists, most famously Emil Gilels. The date of the arrangement is uncertain: it was first published by A. Gutheil of Moscow, and was performed by Siloti in public for the "first time" (according to an announcement in the Manchester Guardian) in February 1912.

The Toccata and Fugue in D minor, BWV 565, is a piece of organ music written, according to its oldest extant sources, by Johann Sebastian Bach. The piece opens with a toccata section, followed by a fugue that ends in a coda. It is one of the most famous works in the organ repertoire. Scholars differ as to when it was composed. It could have been as early as c.1704 (when the presumed composer was still in his teens), which would be one explanation for the unusual features; alternatively, a date as late as the 1750s has been suggested (Bach died in 1750). To a large extent, the piece conforms to the characteristics deemed typical for the north German organ school of the Baroque era with divergent stylistic influences, such as south German characteristics. Despite a profusion of educated guesswork, there is not much that can be said with certainty about the first century of the composition's existence other than that it survived that period in a manuscript written by Johannes Ringk. The first publication of the piece, in the Bach Revival era, was in 1833, through the efforts of Felix Mendelssohn, who also performed the piece in an acclaimed concert in 1840. Familiarity with the piece was enhanced in the second half of the 19th century by a fairly successful piano version by Carl Tausig, but it was not until the 20th century that its popularity rose above that of other organ compositions by Bach. That popularity further increased, due for example to its inclusion in Walt Disney's Fantasia (in Stokowski's orchestral transcription), until this composition came to be considered the most famous work in the organ repertoire. A wide, and often conflicting, variety of analyses has been published about the piece: for instance, in literature on organ music, it is often described as some sort of program music depicting a storm, while in the context of Disney's Fantasia, it was promoted as absolute music, nothing like program music depicting a storm. In the last quarter of the 20th century, scholars such as Peter Williams and Rolf-Dietrich Claus published their studies on the piece and argued against its authenticity. Bach scholars like Christoph Wolff defended the attribution to Bach. Other commentators ignored the authenticity doubts or considered the attribution issue undecided. No edition of the Bach-Werke-Verzeichnis listed the Toccata and Fugue among the doubtful works, nor does its entry on the website of the Bach Archiv Leipzig even mention alternative views on the attribution issue.

The Partitas, BWV 825–830, are a set of six harpsichord suites written by Johann Sebastian Bach, published individually beginning in 1726, then together as Clavier-Übung I in 1731, the first of his works to be published under his own direction. They were, however, among the last of his keyboard suites to be composed, the others being the six English Suites, BWV 806-811 and the six French Suites, BWV 812-817, as well as the Overture in the French style, BWV 831. The six partitas for keyboard form the last set of suites that Bach composed, and are the most technically demanding of the three. They were composed between 1725 and 1730 or 1731. As with the French and English Suites, the autograph manuscript of the Partitas is no longer extant. In keeping with a nineteenth-century naming tradition that labelled Bach's first set of Suites English and the second French, the Partitas are sometimes referred to as the German Suites. This title, however, is a publishing convenience; there is nothing particularly German about the Partitas. In comparison with the two earlier sets of suites, the Partitas are by far the most free-ranging in terms of structure. Unlike the English Suites, for example, wherein each opens with a strict prelude, the Partitas feature a number of different opening styles including an ornamental Overture and a Toccata. Although each of the Partitas was published separately under the name Clavier-Übung (Keyboard Practice), they were subsequently collected into a single volume in 1731 with the same name, which Bach himself chose to label his Opus 1. Unlike the earlier sets of suites, Bach originally intended to publish seven Partitas, advertising in the Spring of 1730 upon the publication of the fifth Partita that the promised collected volume would contain two more such pieces. The plan was then revised to include a total of eight works: six Partitas in Part I (1731) and two larger works in Part II (1735), the Italian Concerto, BWV 971, and the Overture in the French style, BWV 831. The second of these is an eleven-movement partita, the largest such keyboard work Bach ever composed, and may in fact be the elusive "seventh partita" mentioned in 1730. The Overture in the French style was originally written in C minor, but was transposed a half step down for publication to complete the tonal scheme of Parts I and II as described below. The tonalities of the six Partitas (B♭ major, C minor, A minor, D major, G major, E minor) may seem to be irregular, but in fact they form a sequence of intervals going up and then down by increasing amounts: a second up (B♭ to C), a third down (C to A), a fourth up (A to D), a fifth down (D to G), and finally a sixth up (G to E). This key sequence continues into Clavier-Übung II (1735) with the two larger works: the Italian Concerto, a seventh down (E to F), and the Overture in the French style, an augmented fourth up (F to B♮). Thus this sequence of tonalities customary for 18th-century keyboard compositions is complete, beginning with the first letter of his name (B in German is Bach's "home" key of B♭) and ending with the last letter (H in German is B♮) while including both A and C along the way.

Bach - Air on the G String - Music | History "Air on the G String" is August Wilhelmj's arrangement of the second movement in Johann Sebastian Bach's Orchestral Suite No. 3 in D major, BWV 1068. The arrangement differs from the original in that the part of the first violins is transposed down so that it can be played entirely on a violin's lowest string, i.e., the G string. It is played by a single violin (instead of by the first violins as a group). Bach's third Orchestral Suite in D major, composed in the first half of the 18th century, has an "Air" as second movement, following its French overture opening movement. The suite is composed for three trumpets, timpani, two oboes, strings (two violin parts and a viola part), and basso continuo. In the second movement of the suite however only the strings and the continuo play. This is the only movement of the suite where all other instruments are silent. The music of the "Air" is written on four staves, for solo violin, violins, violas, and continuo. The interweaving melody lines of the high strings contrasts with the pronounced rhythmic drive in the bass. In the late 19th century, violinist August Wilhelmj arranged the second movement of Bach's third Orchestral Suite for violin and an accompaniment of strings, piano or organ (harmonium). On the score he wrote auf der G-Saite (on the G string) above the staff for the solo violin, which gave the arrangement its nickname. In Wilhelmj's version the piece is transposed down from its original key (D major) to C major. Then the part of the first violins is transposed further down an octave and given to a solo violin that can play the entire melody on its lowest string, the G string. The dynamic markings added by Wilhelmj are more in line with a romantic interpretation than with the baroque original. As a violin can't play very loudly in its lowest register, all the other parts of Bach's music were firmly reduced in Wilhelmj's version: the keyboard part is to be played staccato and pianissimo, causing the effects of interweaving melodies and of drive in the bass part to get lost. The accompanying violins and violas play muted (con sordino), and the bass part for cellos and double basses is to be played pizzicato and sempre pianissimo, with the same change in effect compared to Bach's original. Later, a spurious story circulated that the melody was always intended to be played on the G string alone. The solo violin part of Wilhelmj's arrangement is sometimes played on the counter-tenor violoncello. As a result of the popularity of the piece, on the G string remained in the name of various arrangements whether or not a string instrument playing on its G string was involved. Most of these versions have in common that the original melody of the first violins is played in the low register of a solo instrument, accompanied by a reduction of the material of the other parts of Bach's piece, although occasionally versions that stay more in line with Bach's original can go by the same name.

Bach - Chorale Preludes BWV 662. Allein Gott in der Hoh' Sei Ehr - Music | History The Great Eighteen Chorale Preludes, BWV 651–668, are a set of chorale preludes for organ prepared by Johann Sebastian Bach in Leipzig in his final decade (1740–1750), from earlier works composed in Weimar, where he was court organist. The works form an encyclopedic collection of large-scale chorale preludes, in a variety of styles harking back to the previous century, that Bach gradually perfected during his career. Together with the Orgelbüchlein, the Schübler Chorales, the third book of the Clavier-Übung and the Canonic Variations, they represent the summit of Bach's sacred music for solo organ. Early versions of almost all the chorale preludes are thought to date back to 1710–1714, during the period 1708–1717 when Bach served as court organist and Konzertmeister (director of music) in Weimar, at the court of Wilhelm Ernst, Duke of Saxe-Weimar. As a result of encouragement from the Duke, a devout Lutheran and music lover, Bach developed secular and liturgical organ works in all forms, in what was to be his most productive period for organ composition. As his son Carl Philipp Emanuel Bach mentions in his obituary or nekrolog: "His grace's delight in his playing fired him to attempt everything possible in the art of how to treat the organ. Here he also wrote most of his organ works." During Bach's time at Weimar, the chapel organ there was extensively improved and enlarged; occupying a loft at the east end of the chapel just below the roof, it had two manual keyboards, a pedalboard and about a dozen stops, including at Bach's request a row of tuned bells. It is probable that the longer chorale preludes composed then served some ceremonial function during the services in the court chapel, such as accompanying communion. When Bach moved to his later positions as Kapellmeister in Köthen in 1717 and cantor at the Thomaskirche in Leipzig in 1723, his obligations did not specifically include compositions for the organ. The autograph manuscript of the Great Eighteen, currently preserved as P 271 in the Berlin State Library, documents that Bach began to prepare the collection around 1740, after having completed Part III of the Clavier-Übung in 1739. The manuscript is made up of three parts: the six trio sonatas for organ BWV 525–530 (1727–1732); the Canonic Variations on "Vom Himmel hoch da komm' ich her" BWV 769 added at the same time as the chorale preludes (1739–1750); and an early version of Nun komm' der heiden Heiland (1714–1717), appended after Bach's death. The first thirteen chorale preludes BWV 651–663 were added by Bach himself between 1739 and 1742, supplemented by BWV 664 and 665 in 1746–7. In 1750 when Bach began to suffer from blindness before his death in July, BWV 666 and 667 were dictated to his student and son-in-law Johann Christoph Altnikol and copied posthumously into the manuscript. Only the first page of the last choral prelude BWV 668, the so-called "deathbed chorale", has survived, recorded by an unknown copyist. The piece was posthumously published in 1751 as an appendix to the Art of the Fugue, with the title "Wenn wir in höchsten Nöthen sein" (BWV 668a), instead of the original title "Vor deinen Thron tret ich hiermit" ("Before your throne I now appear"). There have been various accounts of the circumstances surrounding the composition of this chorale. The biographical account from 1802 of Johann Nicolaus Forkel that Altnikol was copying the work at the composer's deathbed has since been discounted: in the second half of the eighteenth century, it had become an apocryphal legend, encouraged by Bach's heirs, Carl Philipp Emmanuel Bach and Wilhelm Friedmann Bach. The piece, however, is now accepted as a planned reworking of the shorter chorale prelude Wenn wir in höchsten Nöthen sein (BWV 641) from the Orgelbüchlein (c 1715).
