Two equal pipes with mouth-pieces in different positions

Koenig Acoustical · Physics

This instrument consists of two square wooden organ pipes of equal proportions. The first,, is open at one end and has a mouth and round spout at the other. The second,, is similarly open at one end; but at the other, the round spout protrudes vertically from a vertically-set section of the pipe. The mouth of this second pipe is located on the end piece rather than on the body. Velcro has been applied to the bottom surfaces of both pipes.
