Prince Johann Ernst of Saxe-Weimar (1696–1715), a talented musician and composer, was known to be an avid music collector who in 1713 introduced his teacher Johann Gottfried Walther as well as Johann Sebastian Bach to the concerti by Antonio Vivaldi. Both Bach and Walther transcribed different Italian concertos for Prince Johann Ernst’s instruction and enjoyment.

Through these keyboard transcriptions, Bach gained an intimate acquaintance with the Italian concerto style of Vivaldi and his contemporaries. This resulted in sixteen concerti for harpsichord and four organ concerti, drawing on the original orchestral versions by the Italian composers Vivaldi, Alessandro Marcello, Benedetto Marcello, and others. Some are transcriptions from anonymous sources, one by Bach’s contemporary Georg Philipp Teleman, and four from orchestral concertos by the young Prince Johann Ernst of Saxe-Weimar himself.

This Sunday’s postlude in church is Bach’s transcription of a one of Prince Johann Ernst’s compositions: a now-lost violin concerto, composed when the prince was not even 19 years of age!

Trio Sonata No. 3 – Adagio e dolce (BWV 527) – J. S. Bach

Among J. S. Bach’s most important compositions for the organ are the ebullient six Trio Sonatas, BWV 525-530. These pieces were perhaps conceived, and are certainly used, to build technique on an instrument that is played with both hands and feet. Written for the organ or pedal clavichord (a practice instrument for organists), these sonatas require the right and left hands to play independent melodic lines on separate keyboards, while the feet play the basso continuo. The organ sonatas are disarmingly attractive and immediately appealing to the listener, though they pose ferocious interpretive and technical demands for the player. A significant challenge of performing these works is one of sheer coordination: playing three lines of music on two keyboards and pedal with all four limbs. There isn’t much for the performer to cling on to; it’s a little like walking on eggshells.

This Sunday’s prelude in church is the middle movement from the third Trio Sonata (BWV 527), the Adagio (later indicated as Adagio e dolce). Although the Sonata as a whole is in the key of D minor, representing melancholy, devotion and solemnity, this movement is in its relative major key of F, played out as a peaceful, elegant, uncomplicated flute duet.
