Bach probably composed his two extant violin concertos around 1730, not long after he agreed to lead the Collegium Musicum in Leipzig. This talented amateur group gave weekly performances, often in the informal atmosphere of a coffeehouse, providing Bach an outlet for secular music that would not have entered his primary duties preparing music for church services. The violin concertos in A minor and E major were among the works that Bach recast in the late-1730s as keyboard concertos, also intended for the Collegium Musicum. The six keyboard concertos provide evidence that there were likely more concertos for violin, but only the two solo concertos and a double violin concerto in D minor have survived.
Bach borrowed his template for the violin concertos from earlier Italian composers, especially Vivaldi. The E-major Concerto begins with three chords and a pause—a stock opening that can be found in some two dozen of Vivaldi’s concertos—but the ensuing treatment is classic Bach. The recognizable figure of a rising triad spread across three steady beats cascades from voice to voice and passes through a range of keys, making its most striking arrival in the ominous key of C-sharp minor. The journey to that contrasting key area proves even more significant when it turns out to be the home key of the Adagio, a poignant lament the concentrates the richest countermelodies in the lower strings. The Allegro assai finale adheres to the classic ritornello format, in which tutti statements return after each exploratory episode from the soloist.

Johann Sebastian Bach’s Fifth Brandenburg Concerto features flute, violin and harpsichord as soloists. Such a trio was a common chamber music ensemble at the time, playing works known as trio sonatas. What is remarkable about this concerto is that the harpsichord functions as more than a supporting accompanist; it contributes whirlwind solo lines, and it issues a monster of a cadenza at the end of the first movement. This use of the harpsichord as a solo instrument foreshadows the seminal keyboard concertos Bach later assembled in Leipzig.
The middle movement, labeled Affettuoso (“with feeling”), presents the soloists without the accompanying strings. Unlike a trio sonata, in which the harpsichord would typically have just a bass line with the right-hand harmonies filled in ad libitum, the harpsichordist’s right hand plays its own melodic line that intermingles with the flute and violin. In the finale, a fugue reinforces the equal footing of the voices. The violin and flute take the first two entrances, and the harpsichord jumps in with the third and fourth voices of the fugue.

Instead of the typical concerto grosso setup of a solo group within the orchestra, Johann Sebastian Bach’s Third Brandenburg Concerto treats all members of the ensemble as soloists, with independent lines for three violins, three violas and three cellos supported by the basso continuo accompaniment. The equitable distribution of the material is especially clear in the first movement, in which the primary motive — a three-note figure that drops to the lower neighbor note and then returns to the starting pitch — 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.

Bach probably composed the Orchestral Suite No. 1 during his early years in Leipzig, when he first started participating with the Collegium Musicum, an ensemble mainly comprised of university students. With most concerts held at a coffee house, this amateur ensemble provided Bach relief from his rigid church position, letting him experiment with secular music like the four surviving Orchestral Suites inspired by French dance music.
Suites in the French style had become fashionable in Germany, where such a work would have been described as an Ouverture (to use the French spelling), taking the name from the substantial opening movement. The subsequent movements employed dance styles popularized during the reign of Louis XIV, an avid dancer himself. Orchestral suites by Bach and his contemporaries were not intended to accompany actual dancing, but the familiar rhythms and patterns would have contributed to their entertainment value.
