Pipe with moveable lip
Accession Number: 2013.ph.615
This pipe is the mouth-piece of a wooden organ pipe. At the top of the pipe is a wooden spout where air can be blown into the instrument, either by an experimenter, or using apparatus such as a windchest. On the front panel of the pipe is an opening where air flows out of the instrument to produce sound. At the bottom of the pipe is a moveable lip, made of a thin slab of pine. This piece of wood can be moved to vary the opening of the pipe. By closing the gap, the pitch emitted by the pipe rises.
