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.

Orchestration: solo keyboard and strings First Los Angeles Philharmonic performances Ever since the first biography of Johann Sebastian Bach appeared in , commentators have generally underestimated the importance of his seven surviving keyboard concertos. Johann Nikolaus Forkel, the author of that biography, described the concertos as follows: "Notwithstanding the treasure of art which they contain, they are antiquated as regards their form and their setting in other respects.
Albert Schweitzer comes down much more harshly on the concertos in his biography of the composer, describing them as "arrangements made with quite incredible haste and carelessness. Taken as a group, the concertos actually display many forward-looking characteristics alongside their more conservative ones. Perhaps the most obvious of these is that they were among the earliest works for keyboard and orchestra, and certainly the earliest to endure in the repertory today.
And none of the seven concertos more nearly approaches what came after them than the D major, BWV Bach composed the D-major Concerto during his period in Leipzig - scholars date it to about because Bach copied all seven of his keyboard concertos out in - when, in addition to his duties at St.
In its new version as a work for keyboard and string orchestra, the concerto was intended for the Collegium, and the solo part may have originally been played by Bach himself, or by one of his sons.
The D-major Concerto opens with a tripartite A-B-A structure stretched to the point of nearly being a movement in sonata form. In the A section, Bach introduces the essential thematic material of the movement, and he treats this to a series of elaborate variations in the extended B section, which basically functions as a development would in sonata form.

The piano spins out an elegant melody over a chaconne-like bass figure in the strings that Bach varies slightly each time it repeats itself during the course of the movement.
