Mouthpiece of Organ Pipe

Koenig Acoustical · Physics

This piece resembles a wooden organ pipe with the back cut away. A round spout protrudes from one end. A slat of wood has been placed into the body of the pipe so that it can slide down to cover the opening of the lip.

Primary Materials: Wood (Pine)


A number has been handwritten on the base of the pipe, near the mouthpiece. It appears to read perhaps “14”. On other pipes in this collection, this number refers to the pipe’s entry in Koenig’s 1873 catalogue.

Dimensions (cm): Height = 33, Width = 6.5, Length = 3.5


To demonstrate how closing the lip opening of a pipe results in a higher pitch.

According to David Pantalony’s “Altered Sensations” (2009): “A thin slab of pine slides into the opening of the lip. As it closes the gap, the sound of the whistle clearly rises in pitch.”


Very good. Some minor scratches and abrasions on the body of the piece. Velcro strips have been affixed to the back.
