"Nun komm der Heiden Heiland" à 2 Clav.

Even if it has just been published (and "si parva licet componere magna" ...) I would like to upload my double version of this famous Bach choral - this evening Advent begins.
On the interpretation of this piece I know two "schools of thought": personally I have always performed it as in the first version, slow and meditative, but a few years ago an Italian-Swiss organist friend, hearing me play it, asked me point blank " ... so slow? We use it here as an introduction to the choral ... ". Since then I have tried to conceive of it as if the choral line was actually sung by a soprano, playing it much faster and treating the accompaniment as if it were played by an orchestral string section: I have to say I like it both ways. It is like saying the same thing in different ways: one intimate and engrossed in the face of the enormity of the mystery of the Incarnation, the other almost "impatient" to see the fulfillment of the ancient promise.
For the first version (00:03) I found Azzio's little Mascioni still very suitable, with the same stops I had used for Ich ruf 'zu Dir; while for the second (04:50) I relied on the more rounded sounds of Lipiny's Volkmann - making the Cornetto of the first manual sing.
A little experiment that I hope enjoyable!
