Standards
When building your instrument the existing, accepted standards in organ building are taken
into account, wherever possible. The two most important standards are:
1. The BDO standard.
BDO stands for Bund Deutscher Orgelbaumeister. Instruments for the European
continent are usually built according to this standard.
2. The AGO standard.
AGO stands for American Guild of Organists. Instruments for the Anglo-Saxon
countries and the USA are usually built according to this AGO standard.
The most striking characteristic of AGO instruments is the design of the pedalboard. In
contrast to the BDO instruments, AGO instruments do not know a straight or concave
pedalboard but have always a concave pedalboard whose keys fan out to the front (radial).
Another striking difference between BDO and AGO instruments is the order of stops.
Order of Stops
In making the order of stops, a number of factors have to be taken into account:
! The organ building standards
! The available space on the stop jambs
! The symmetry between the left and the right stop jambs.
! The position of the accessories
! Determining the position of the stop groups belonging to a division (keyboard)
! Determining the order of stops per division, the footage of a stop and the family to which
a stop / accessory belongs must be taken into account.
Standards
The order of stops will have been made, as much as possible, according to the standards
applicable to your instrument.
Available space and symmetry
The available space is especially important for the Monarke models "Van Rhijn",
"Gothique", "Positief" and "Van Eyck". On these instruments the stops have to be placed
relatively far apart due to add name plates, and for ease of operation.
These models have no space to place the accessories as a separate group of stops under
the music desk.
To achieve a good symmetry between the left and right stop console and utilizing the space
optimally, the Monarke models "Van Rhijn", "Gothique", "Positief" and "Van Eyck" are fitted
with one of the (BDO) order of stops as shown in the diagram on the next page:
