Bach adapted this concerto from the opening Sinfonia of a secular cantata from 1713, Was mir behagt, ist nur die muntre Jagd (“The lively hunt is all my heart’s desire”). The first movement retains the jovial, outdoor ambience of music inspired by the hunt, with the horns issuing calls to action, sometimes in triplets that contradict the orchestra’s pulse, as if they have already moved ahead in the hunt at their own pace. After this spirited opening, the Adagio movement is a poignant departure, featuring the oboe, solo violin and bass group elaborating a plaintive melody. An oboe cadenza and a series of mysterious chords lead into the third movement, a sprightly romp that shows off the solo violin’s bright figurations.

In the Allegro first movement, the solo violin takes the flashiest material, including long strings of arpeggios, a series of double-stops (the technique of playing two notes at once) and a wickedly fast passage of slurred 32nd-notes. The characteristic tone of the flutes becomes more prominent in the middle movement, when the soloists contribute airy echoes to the ensemble’s phrases, with the violin dropping into the role of the bass instrument to support the higher voices. The movement ends on an unresolved chord that wants to settle on E minor, the slow movement’s home key, but instead the violas launch the Presto finale in G, where the concerto started. Their robust phrase marks the start of a fugue, which intersperses virtuosic solo episodes among the passages of formal counterpoint.

The equitable distribution of the material is especially clear in the first movement, in which a three-note figure cascades through the different voices. The central Adagio movement consists simply of two linking chords, sometimes elaborated by an improvised cadenza. The concerto closes with a barreling Allegro finale, its tempo and character matching the reeling gigues that conclude most of Bach’s dance suites.
