This rectangular wooden organ pipe exhibits a round spout and a mouth at one end and is open at the other. In the centre of the pipe, two slits have been cut though opposite sides so that a slat may be inserted through the pipe. A large hole has been cut into this slat, and it may be adjusted so that the node is either open or closed. Velcro strips have been applied to the bottom surface.
Accession Number: 2013.ph.616

On the top of the pipe near the spout: “83”. Near the mouth: “RUDOLPH KOENIG A PARIS”. On the slat, in pencil: “83”.

This instrument is intended to demonstrate how, if an organ pipe is fully closed at the middle node, it will play the same note as though it were open.
Very good. Some minor chips and scratches on the body of the pipe.
