One of my favorites. No turn of the year without this famous chorale from the Orgelbüchlein. Although it has been posted here many times before, I take the liberty of sharing my interpretation with you.
Silbermann Petrikriche
I Viol di Gamba 8', Rohrflöte 8'
II Gedackts 8', Quintadena 8', Naßat 3'
Ped Principalbass 16'
