Like Johann Sebastian Bach's better known Concerto in D
minor, this work is thought to be a transcription of a
lost concerto. While some scholars have attributed the
violin composition to Vivaldi or to a minor German
composer, the counterpoint and structure of the clavier
seem indicative of Bach's idiom. Written during Bach's
Cöthen period, the concerto is in three movements; all
three are in ritornello form, in which each movement is
based upon a single theme restated in various
orchestrations at the opening, the closing, and after
each exploratory section.
This, the slow second (Adagio) movement, in the
relative major of A flat, begins with a lengthy and
elaborate 21-bar arabesque, lightly accompanied by a
sparse bass figure of eighth notes. The frequent and
extensive ornamentation in the melody make this
movement somewhat rococo in character.
Although this piece was originally written for
Harpsichord, I created this arrangement for Two (2)
Concert (Pedal) Harps.
