This organ is situated high on the wall column between the Saint-Joris Chapel and the Weitkopers Chapel. It is known as the transept organ or small organ. The current instrument was built by the Ahrend & Brunzema in 1965, within a case dating from 1658–1659, and is the fourth organ at this spot. The first ‘Edammer werck’ organ was located here until 1544, from 1544 the second organ built by Hendrick Niehoff, and from 1567 the third organ realized by Pieter Jansz de Swart. The original function of the choir organ was to accompany choral and congregational singing.
