Ciaconna "Jesus Christus unser Heiland, der von uns"

Manuscript Mus ms 40037, owned by the Staatsbibliothek Berlin, contains 5 chorale preludes to "Jesus Christus, under Heiland, der von uns". Three of them were composed by Zachow, two remain anonymous. Though there is no indication of a composer for both of these preludes, I think it is safe to say that both were composed by the same anonymous composer. This anonymous composer saw that each of the four phrases of the melody of this choral can have the same harmonisation. He used this characteristic of the chorale melody to write two Ciaconsas.

The first of these two is for two manuals and pedals. The eigth bars long introduction for left hand and feet is the accompaniment for each of the four phrases of the chorale melody, played on a different manual with a solo registration.

The recording was done with the Hauptwerk software and the sampleset, made by Voxus, of the Matthijs van Deventer-orgel in the Grote Kerk, Nijkerk (https://www.voxusorgans.com/en/product/nijkerk).
