The St. Thomas church possessed in addition a small organ. This instrument, at one time abandoned, and later again brought into service, stood at Bach's time in a gallery, opposite the large organ. It possessed a stop called Trichter-Regal, a sort of Vox humana. This organ was used in performance of the St. Matthew Passion music, in coöperation with the other.
