east side of the north arm of the "transept" in the Danse Macabre Chapel (so named because of the Danse Macabre painting that hung there) and was used for the musical accompaniment of the requiem masses that were celebrated there. After the Church Reformation it was used for prayers and for Holy Communion services. In 1549 and 1558 Jakob Scherer added to the organ among other things, a chair organ (), and in 1621 a chest division was added. Friedrich Stellwagen also carried out extensive repairs from 1653 to 1655. Thereafter, only minor changes were made. For this reason, this organ, together with the Arp Schnitger organ in St. James' Church in Hamburg and the Stellwagen Organ in in Lübeck, attracted the interest of organ experts in connection with the Orgelbewegung. The of the organ was changed back to what it had been in the 17th century. But, like the main organ, this organ was also destroyed in 1942. In 1955 the organ builders Kemper & Son restored the Danse Macabre organ in accordance with its 1937 dimensions, but now in the northern part of the ambulatory, in the direction of the raised choir. Its original place is now occupied by the astronomical clock. This post-War organ, which was very prone to malfunction, was replaced in 1986 by a new Danse Macabre organ, built by Führer Co. in Wilhelmshaven and positioned in the same place as its predecessor. It has a mechanical tracker action, with four manuals and a pedalboard, 56 stops and approximately 5,000 pipes. This organ is particularly suited for accompanying prayers and services, as well as an instrument for older organ music up to Bach. As a special tradition at St Mary's, on New Year's Eve the chorale Now Thank We All Our God is accompanied by both organs, kettledrums and a brass band. Other instruments There used to be an organ on the rood screen, as a basso continuo instrument for the choir that was located there – the church's third organ. In 1854 the breast division that was removed from the Great Organ (built in 1560–1561 by Jacob Scherer) when it was converted was installed here. This "rood screen organ" had one manual and seven stops and was replaced in 1900 by a two-manual pneumatic organ made by the organ builder Emanuel Kemper, the old organ box being retained. This organ, too, was destroyed in
