Title page of D-B Mus.ms. Bach P 804, Fascicle 19, Johann Peter Kellner's manuscript copy of the Prælude in C mol: pour La Lute.[1]
The Prelude in C Minor, BWV 999, is, according to its only extant 18th-century manuscript, a composition for lute by Johann Sebastian Bach. In the manuscript, conserved as Fascicle 19 of Mus.ms. Bach P 804 at the Berlin State Library, Johann Peter Kellner wrote the piece down in keyboard notation. The time of origin of the work is not known: possibly Bach composed it in his Köthen period, that is, between 1717 and 1723, or the early years of his ensuing Leipzig period. Kellner's copy was produced after 1727, but before Bach's death in 1750.
The Prelude can be performed as well on a lute as on a keyboard. In the 19th century, it was adopted as No. 3 in the keyboard collection Twelve Little Preludes. It was grouped with Bach's lute compositions in 20th-century scholarship such as the Bach-Jahrbuch of 1931, the Bach-Werke-Verzeichnis and the New Bach Edition. It has been recorded in performances on lute, on guitar, and on keyboard instruments such as piano or harpsichord. In the 21st century, digital facsimiles of Kellner's copy became available on-line, for instance at the Bach Digital website.
According to Kohlhase, Johann Peter Kellner's copy of the Prelude dates from around the middle of the 1720s.[5] A more comprehensive research into the time of origin of all 57 fascicles of the Berlin State Library's Mus.ms. Bach P 804 convolute, by Russell Stinson, showed that its 19th fascicle, Kellner's copy of the BWV 999 Prelude, originated after 1727.[6] All fascicles of the P 804 manuscript were written before Bach's death in 1750.[7] Kellner's manuscript is the only source for the composition.[8][9]
The title page of Kellner's copy of BWV 999, page 101 in the D-B Mus.ms. Bach P 804 convolute, reads:[1][8]

The composition is written on the next two pages, on systems of two staffs, with a soprano clef for the upper staff, and a bass clef for the lower staff. Although, in the first half of the 18th century, a tablature notation was common for lute compositions, Kellner thus wrote the Prelude down in a notation which at the time was customary for keyboard compositions.[10] The Prelude can be performed as well on a keyboard instrument as on a lute.[11][12][13] Kellner is known as an organist and keyboard performer: his copy of BWV 999 is the only extant instance of him taking an interest in a composition for lute.[11]

A concluding section, which could follow after the Prelude as written down by Kellner, seems to be missing. The Prelude opens in C minor but instead of returning to that key (i.e., the tonic), it ends on the dominant, in fact the parallel key of the dominant, G major, while the closing chord contains a Picardy third. David Schulenberg [fr] compares this to the Prelude BWV 872a/1: after a section with arpeggios ending on the dominant, it continues with a fugato returning to the tonic. Also, the last bar of the piece only has the duration of a quarter note: it is uncommon for a piece in 3 4 to end on a bar with a different duration than three quarter notes. Whether Bach never composed such continuation of the piece, or whether Kellner didn't copy it, is not known.[11]
Music
BWV 999's brief, introductory nature (43 measures), improvisatory feel and reiteration of a defining motif fits squarely within the prelude genre of the 1710s and 1720s. Additionally, the shortness of the motif itself follows the conventions of early sixteenth-century prelude. It also served a teaching purpose characteristic of the genre, widely using arpeggiations and technical demands that served students well as an étude. Barbara Russano Hanning describes prelude features and goals: "The typical prelude assigns the player a specific task, so that the piece functions as an etude. In addition, the preludes illustrate different types of keyboard performance conventions and compositional practices."[14] Such pedagogical traits contribute to the work's longevity; it is still an oft-used educational tool.[citation needed]
The Prelude's central motif consists of intersecting rhythms between the upper and lower voice (what originally would have been the left and right hand). In the right hand, this is a sixteenth rest, followed by a seven-note sixteenth passage that typically arpeggiates an inversion of a triad (ascending and descending from and back to the root), and an alternating sixteenth rest–sixteenth note pattern in the third beat. The left participates by having a pedal tone quarter in the first beat, a rest, then two eighth notes. The ascending and descending triad in Bach's prelude BWV 999 seem to have been the true inspiration and chord structure for the arpeggios in the Beatles song Because, because when the prelude is played at half-speed and on harpsichord, the similarity is striking, especially at measures 8–9–11, about 15 seconds into the prelude, with the repeating notes at the end of the interval being eliminated in the Beatles version.
Measures 8–14 (modulation occurring in mm. 11–14 is highlighted]).
Contrary to its title and key signature, less than a third of BWV 999 is actually written in C minor. In measure 11, a Secondary leading-tone chord is employed (namely, a diminished F♯ seventh chord) to modulate and lead the ear to G minor, the dominant of the original key. Aside from a turn to G major but with a flattened 6th (mm. 34–38 and 42–43), and the reemergence of C minor (mm. 39–41), G minor tonality dominates the piece. Early on, the upper voice is repeated over several measures, with the left hand providing the only shifting harmonic background. For example, measures 8–10 are exactly the same in the right hand, but descending tones in the left hand create an expansion of tonic harmony.
Vorzüglich ist ein kleines C moll-Praeludium, das harfenartig lispelnd von einer Harmonie zur andern träumt und die wundersame Romantik des Bachschen Geistes ahnungsvoll emporsteigen läßt
Very admirable is a little prelude in C minor, which runs whispering on in harp-like tones from one set of harmonies to another, and yet lets the mystical romanticism of Bach's genius pierce through it all.
Spitta, assuming that nearly none of Bach's compositions for lute survived, mentioned the third of the Twelve Little Preludes as composed for lute or keyboard.[20][21] The Bach Gesellschaft retained the Twelve Little Preludes set for keyboard in the 36th volume, published in 1890, of their complete edition of Bach's works.[3][15][22]
Auch diese Komposition liegt der Laute in alter Stimmung sehr günstig und ist ausgezeichnet spielbar. Die vorzüchliche Einrichtung erweist den Komponisten als mit der Lautentechnik sehr bewandert.
Also this composition suits the lute tuned in the old fashion very well, and is very playable. The proficient setting shows that the composer was very versed in lute technique.
Neemann identified five more compositions by Bach as intended for lute.[24] In the Bach-Werke-Verzeichnis, first published in 1950, these compositions were grouped in the BWV 995–1000 range, in a section for lute works.[25] The same six compositions were published in Series V, Vol. 10, of the New Bach Edition, in 1976.[26]
The Prelude has been adapted for various instruments, including lute, piano and guitar. It is a pedagogical work much in the spirit of The Well-Tempered Clavier, with which it shares musical characteristics.[citation needed] In the second decade of the 21st century, digital facsimiles of Kellner's manuscript became available on the Berlin State Library and Bach Digital websites.[1][5]
Recordings
Some guitarists perform the Prelude BWV 999 in D minor instead of in its original key of C minor (but they can however use D Standard Tuning so that when they play in D Minor, it sounds as the Original C Minor).[27][28][29][30][31][32][33][34][35]
