I finally sat down to sketch out the designs for the three types of organ pipes I’ll be building on graph paper.
Diapasons have simple mouths – a 10 degree upper lip over a 15 degree lower lip. Flutes have ears – faceplates that stick out on either side of the mouth which ensures prompt speech with a 10 degree upper lip over a flat lower lip. Strings have beards – wooden dowels placed in front of the mouth that slows speech over a 10 degree upper lip over a 15 degree lower lip.
The languids are all different shapes – diapasons have angular windways while flutes have slightly rounded windways. Strings have fully rounded windways.
