ABSTRACT:
A converter allows one to use common PVC pipes for making a musical pipe. The converter has a beveled edge such that one need not provide a separate beveled edge tube for each note, but one may simply use the same converter on various tubes of different lengths in order to produce different notes. The converter is used to produce a calliope pipe. A valve arrangement cooperates with the converter and sound pipe in order to allow one to individually control the sound of a particular musical or sound pipe.
