The opening movement is an Allegro in A major and. Mostly light and nimble in spirit, the movement starts with a bar ritornello broken up into two halves, each 8 bars long. In the first solo episode, the harpsichord introduces its own more sustained thematic material as well as semiquaver passagework derived from the end of the second half of the ritornello. All the harpsichord solo passages are based on or develop this thematic material. The two bar "motto" or Vordersatz opening the ritornello, consisting of rhythmic spiccato quaver figures in the strings and cascading broken chord semiquavers in the harpsichord, recurs throughout the movement, heralding solo episodes for the harpsichord. In the remainder of A section, the second episode is introduced by the two bar motto and followed by a reprise of the entire first half of the ritornello.

See media help. The definitive version BWV was recorded by Bach himself in the autograph manuscript of all eight harpsichord concertos BWV —, made around In these cantata versions the orchestra was expanded by the addition of oboes. Beginning with Wilhelm Rust and Philipp Spitta , many scholars suggested that the original melody instrument was the violin, because of the many violinistic figurations in the solo part—string-crossing, open string techniques—all highly virtuosic.

Williams has speculated that the copies of the orchestral parts made in BWV a might have been used for a performance of the concerto with Carl Philipp Emanuel as soloist. Both relate the work to performances by Bach of concerted movements for organ and orchestra in Dresden and Leipzig. He abandoned the next entry BWV after only a few bars to begin setting down BWV with a far more comprehensive approach to recomposing the original than merely adapting the part of the melody instrument.

Both start in the manner of Vivaldi with unison writing in the ritornello sections—the last movement begins as follows: [23] [24] Bach then proceeds to juxtapose passages in the key of D minor with passages in A minor: in the first movement this concerns the first 27 bars; and in the last the first 41 bars.

These somewhat abrupt changes in tonality convey the spirit of a more ancient modal type of music. In both movements the A sections are fairly closely tied to the ritornello material which is interspersed with brief episodes for the harpsichord. The B section in the first movement starts with repeated note bariolage figures: [23] [24] which, when they recur later, become increasingly virtuosic and eventually merge into brilliant filigree semidemiquaver figures—typical of the harpsichord—in the final extended cadenza-like episode before the concluding ritornello.

In the first movement the central section is in the keys of D minor and E minor; in the last movement the keys are D minor and A minor. As in the opening sections, the shifts between the two minor tonalities are sudden and pronounced. In the first movement Bach creates another equally dramatic effect by interrupting the relentless minor-key passages with statements of the ritornello theme in major keys. Jones describes these moments of relief as providing "a sudden, unexpected shaft of light.

More generally Jones has pointed out that the predominant keys in the outer movements centre around the open strings of the violin. Its first publication in print was in by the Kistner Publishing House.
