Brandenburg Concerto No. 3

This work is part of a collection of six “Brandenburg Concertos” written by Bach in the early 18th century, probably between 1708 and 1721. While probably not conceived as a unitary set of works, Bach gathered all of them together and sent them, together with a dedication, to the Margrave of Brandenburg in 1721 (evidently in pursuit of a musical position). While his job search didn’t pan out, his Brandenburg concerti – only rediscovered in the Brandenburg library and published in 1850 – have since become world-famous.

Each of the concerti is scored for a different combination of string and wind instruments. Brandenburg Concerto No.3 is scored for strings and continuo (cembalo), but with a twist – there are three separate parts for each section (violins, violas and cellos), together with a unifying bass and cembalo part. The result is an intriguing combination of unified orchestral playing interspersed with separate solo lines. Bach himself is said to have played the first viola part in this work, leading the ensemble from that position.

The first movement’s vigorous opening is the basis for all of the other melodic and contrapuntal elements in the movement, with motifs traded back and forth between and within violins, violas, and cellos. For the second movement, Bach only wrote two long chords to be played by the strings. While occasionally played that way, another view is that he intended an improvisatory passage to be played leading into those chords, either by a solo violin or solo keyboard. For today’s performance we have adapted a short passage from a Bach keyboard work to be played on the harpsichord as a bridge to the last movement. The concluding allegro is a rollicking gigue-like dance featuring non-stop contrapuntal lines among the string sections, with notable violin and viola solos.
