The Goldberg Variations, BWV 988, is a work written for harpsichord by Johann Sebastian Bach, consisting of an aria and a set of 30 variations. First published in 1741, the work is considered to be one of the most important examples of variation form. The Variations are named after Johann Gottlieb Goldberg, who may have been the first performer. The tale of how the variations came to be composed comes from an early biography of Bach by Johann Nikolaus Forkel:[1] [For this work] we have to thank the instigation of the former Russian ambassador to the electoral court of Saxony, Count Kaiserling, who often stopped in Leipzig and brought there with him the aforementioned Goldberg, in order to have him given musical instruction by Bach. The Count was often ill and had sleepless nights. At such times, Goldberg, who lived in his house, had to spend the night in an antechamber, so as to play for him during his insomnia. … Once the Count mentioned in Bach's presence that he would like to have some clavier pieces for Goldberg, which should be of such a smooth and somewhat lively character that he might be a little cheered up by them in his sleepless nights. Bach thought himself best able to fulfill this wish by means of Variations, the writing of which he had until then considered an ungrateful task on account of the repeatedly similar harmonic foundation. But since at this time all his works were already models of art, such also these variations became under his hand. Yet he produced only a single work of this kind. Thereafter the Count always called them his variations. He never tired of them, and for a long time sleepless nights meant: 'Dear Goldberg, do play me one of my variations.' Bach was perhaps never so rewarded for one of his works as for this. The Count presented him with a golden goblet filled with 100 louis-d'or. Nevertheless, even had the gift been a thousand times larger, their artistic value would not yet have been paid for. Forkel wrote his biography in 1802, more than 60 years after the events related, and its accuracy has been questioned. The lack of dedication on the title page also makes the tale of the commission unlikely. Goldberg's age at the time of publication (14 years) has also been cited as grounds for doubting Forkel's tale, although it must be said that he was known to be an accomplished keyboardist and sight-reader. Williams (2001) contends that the Forkel story is entirely spurious. Arnold Schering has suggested that the aria on which the variations are based was not written by Bach. More recent scholarly literature (such as the edition by Christoph Wolff) suggests that there is no basis for such doubts. Rather unusually for Bach's works,[2] the Goldberg Variations were published in his own lifetime, in 1741. The publisher was Bach's friend Balthasar Schmid of Nuremberg. Schmid printed the work by making engraved copper plates (rather than using movable type); thus the notes of the first edition are in Schmid's own handwriting. The edition contains various printing errors.[3] The title page reads in German: Clavier Ubung / bestehend / in einer ARIA / mit verschiedenen Verænderungen / vors Clavicimbal / mit 2 Manualen. / Denen Liebhabern zur Gemüths- / Ergetzung verfertiget von / Johann Sebastian Bach / Königl. Pohl. u. Churfl. Sæchs. Hoff- / Compositeur, Capellmeister, u. Directore / Chori Musici in Leipzig. / Nürnberg in Verlegung / Balthasar Schmids[3] (English translation: Keyboard exercise, consisting of an ARIA with diverse variations for harpsichord with two manuals. Composed for connoisseurs, for the refreshment of their spirits, by Johann Sebastian Bach, composer for the royal court of Poland and the Electoral court of Saxony, Kapellmeister and Director of Choral Music in Leipzig. Nuremberg, Balthasar Schmid, publisher.) The term "Clavier Ubung" (nowadays spelled "Klavierübung") had been assigned by Bach to some of his previous keyboard works. Klavierübung part 1 was the six partitas, part 2 the Italian Concerto and French Overture, and part 3 a series of chorale preludes for organ framed by a prelude and fugue in E♭ major. Although Bach also called his variations "Klavierübung", he did not specifically designate them as the fourth in this series. Nineteen copies of the first edition survive today. Of these, the most valuable is the "handexemplar", discovered in 1974 in Strasbourg by the French musicologist Olivier Alain and now kept in the Bibliothèque nationale de France, Paris. This copy includes printing corrections made by the composer, and additional music in the form of fourteen canons on the Goldberg ground (see below). The nineteen printed copies provide virtually the only information available to modern editors trying to reconstruct Bach's intent, as the autograph (hand-written) score has not survived. A handwritten copy of just the aria is found in the 1725 Notebook for Anna Magdalena Bach. Christoph Wolff suggests on the basis of handwriting evidence that Anna Magdalena copied the aria from the autograph score around 1740; it appears on two pages previously left blank. The aria is a sarabande in 3/4 time, and features a heavily ornamented melody. The French style of ornamentation suggests that the ornaments are supposed to be parts of the melody; however, some performers (for example Wilhelm Kempff on piano) omit some or all ornaments and present the aria unadorned. Peter Williams opines in Bach: The Goldberg Variations that this is not the theme at all, but actually the first variation (a view emphasising the idea of the work as a chaconne rather than a piece in true variation form).
