Bach’s music uniquely visualized by Stephen Malinowski.
The vertical stripes show the rhythmic “grid” — showing the hierarchy of beats. The first beat in a measure is the strongest, followed by the half-measure point, followed by quarter-measure points, etc. This lets you see when a note is “suspended” through a strong beat.
One of my favourites from Book II.
The Well-Tempered Clavier (German: Das Wohltemperierte Klavier),[2] BWV 846–893, is a collection of solo keyboard music composed by Johann Sebastian Bach. He first gave the title to a book of preludes and fugues in all 24 major and minor keys, dated 1722, composed “for the profit and use of musical youth desirous of learning, and especially for the pastime of those already skilled in this study.” Bach later compiled a second book of the same kind, dated 1742, but titled it only “Twenty-four Preludes and Fugues.” The two works are now usually considered to make up a single work, The Well-Tempered Clavier, or “the 48,” and are referred to respectively as Books I and II.[3] The Well-Tempered Clavier is generally regarded as one of the most influential works in the history of Western classical music.[3]
Take a baroque and enjoy some Bach ;)
Same ground base, 20 variations, 1 bar ending. The brilliance of Bach on display.
BWV 582/1: Passacaglia
The passacaglia is in 3/4 time typical of the form. Bach’s ostinato comprises eight bars, which is unusual but not unheard of: an ostinato of the same length is used, for example, in Johann Krieger‘s organ passacaglia. The opening of the piece, which consists of the ostinato stated in the pedal with no accompaniment from the manuals, is slightly more unusual, although this idea also occurs elsewhere, and may even have been used by Buxtehude.[8]
There are 20 variations in BWV 582/1. The first begins with a typical C minor affekt, “a painful longing” according to Spitta, similar to the beginning of Buxtehude’s Chaconne in C minor (BuxWV 159).[9] Numerous attempts have been made to figure out an overarching symmetrical structure of the work, but scholars have yet to agree on a single interpretation.[10] Particularly important attempts were made by Christoph Wolff and Siegfried Vogelsänder.[11] Some scholars have speculated that there is a symbolic component to the structure of the work: for instance, Martin Radulescu argues that BWV 582/1 is “in the form of a cross”.[12]
There is agreement among most scholars that the Passacaglia builds up until its climax in variation twelve.This is followed by three quiet variations, forming a short intermezzo, and then the remaining five variations end the work.
Bach performer and scholar Marie-Claire Alain suggested that the 21 variations are broken down into 7 groups of 3 similar variations, each opening with a quotation from a Lutheran chorale, treated similarly to the Orgel-Buchlein written at a similar time:[13]
- Bars 8-12, the top part spells out the opening notes of “Nun komm’ der Heiden Heiland”
- Bars 24-48, a cantilena spells out “Von Gott will ich nicht lassen”
- Bars 49-72, the scales are a reference to “Vom Himmel kam der Engel Schar”
- Bars 72-96, recalling the “star” motif from “Herr Christ, der Ein’ge Gottes-Sohn”
- Bars 96-120, ornamented figure similar to that in “Christ lag in Todesbanden” accompanies theme in the soprano then moving successively to alto and bass
- Bars 144-168 “Ascending intervals in bass recall the Easter chorale “Erstanden ist der heil’ge Christ”.
Alain also points out that the numbers (21 repetitions of the Passacaglia ground and 12 statements of the fugue subjects) are inversions.
BWV 582/2: Fugue
The passacaglia is followed, without break, by a double fugue. The first half of the passacaglia ostinato is used as the first subject; a transformed version of the second half is used as the second subject.[14] Both are heard simultaneously in the beginning of the fugue. A countersubject enters immediately afterwards and is then used throughout the piece. When the three subjects appear simultaneously, they never do so in the same combination of voices twice; this therefore is a permutation fugue, possibly inspired by Johann Adam Reincken‘s works.[15]
As the fugue progresses, Bach ventures into major keys (Eb and Bb) and the time between the statements increases from 1-3 bars to 7-13. This expansion culminates in a Neapolitan sixth chord that leads into the 8 bar coda.
The Orgelbüchlein (“Little Organ Book”) was written by Johann Sebastian Bach during the period of 1708–1714, while he was court organist at the ducal court in Weimar. It was planned as a set of 164 chorale preludes (smaller-scale compositions based on chorale melodies) spanning the liturgical year; however, Bach only completed forty-six chorale preludes and left less than two measures of a forty-seventh. The chorale preludes in this collection constitute BWV 599–644 within Bach’s total compositional output. The Orgelbüchlein is at the same time a collection of organ music for church services, a treatise on composition, a religious statement and a pedagogical manual.
| “ | A further step towards perfecting this form was taken by Bach when he made the contrapuntal elements in his music a means of reflecting certain emotional aspects of the words. Pachelbel had not attempted this; he lacked the fervid feeling which would have enabled him thus to enter into his subject. And it is entering into it, and not a mere depicting of it. For, once more be it said, in every vital movement of the world external to us we behold the image of a movement within us; and every such image must react upon us to produce the corresponding emotion in that inner world of feeling. | ” |
