The melody of this choral is also known with the words “Freu dich sehr, o meine Seele”. That seems an interesting contrafact, since based on the incipit the meaning is totally different. I should of course look up the complete text of this choral. My interpretation in tempo and registration is based solely on the first words. Not really scholarly, but I like the result.
The recording was done on the sample set of the Müller-organ in the Sint Bavokerk in Haarlem by Voxus Organs for Hauptwerk.
HW: Roerfluit 8′, Octaaf 4′
