The Gallery Organ
Built by Pels & van Leeuwen, Orgelmakers
Alkmaar, the
Netherlands
The gallery organ in Dimnent Memorial Chapel was built in
1970 in the style of the 17th and 18th century Dutch organ.
Its pipes and action are self-contained in an oak case with speaking pipes
forming a prospect across the front opening. The key action is completely
mechanical, and the wind pressure is low. The organ has three divisions: the
Bovenwerk, played on the upper keyboard; the Hoofdwerk, the main division
played on the lower keyboard, and the Pedaal. The principal rank of pipes for
each of these divisions is called the Prestant ('show pipes'), and is located
in the organ's case. As one looks at the front of the instrument the location
of the pipes for each division becomes clearly apparent: the two 'side
towers' house the Pedaal, the upper central section houses the Bovenwerk
('upper works'), and the lower central section houses the Hoofdwerk.
