Organ Pipe Designs

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.
