Johann Sebastian Bach (1685 - 1750) wrote some of the concertos for keyboard and strings. He wrote seven for solo keyboard and strings and wrote others for 2, 3 and 4 harpsichords. All of the solo concertos are transcriptions of Bach's own concertos for solo melody instrument such as violin. In many cases it is only the harpsichord transcription that survives complete. The D minor concerto, BWV 1052, seems Bach use the same music for strings as in the original violin concerto while the solo part is filled out harmonically from the solo violin part of the original. Bach obviously strove to make the keyboard version as virtuosic as the violin version. Bach was familiar with his contemporary Vivaldi's concertos and they exerted a large influence on Bach's concerto style.
Comparing Bach's another harpsichord concerto No.8 in d minor, BWV 1059, there are many similarities and differences. For No.8, it is an incomplete piece. only 9 bars survived. Like nearly all of Bach's harpsichord concertos, this is and adaptation of a concerto written for an oboe and the melody parts taken from his cantata. The first movement is marked as Allegro. The second movement, like the No.1, is a very expressive Adagio and the last movement is Presto.
For me, as a piano major students, I always love Bach's music, especially his keyboard works. Bach produces a pece perfectly designed for harpsichord. Even if the harpsichord has had its time, it certainly isn't forgotten because of this greatness of compositions made for its amazing dynamics and unique tone.
