Circular Pipe Giving Sounds

Koenig Acoustical · Physics

This piece consists of a rectangular wooden pipe in a round, wreath-like shape. A round mouthpiece protrudes from one side. On the body of the pipe are six wooden levers labelled with various numbers, which may be opened or closed to expose holes in the pipe. A sliding door divides the pipe in half and creates a node at that point. Pieces of velcro have been applied to one end.

Very good. There are minor chips and scratches on the body of the pipe. The sliding door is jammed, and the whole piece is very slightly warped. The varnish has worn off in places.
