Tips	Move the stoppers in the wooden organ pipe and in the plastic one. This provides a perfect example of the relationship between the length of an air column and the frequency of the sound produced. For convenience, the stopper handle, in the wooden organ pipe, is marked with the correct settings for playing notes from middle C to treble C. To operate the metal organ pipe slip the mouthpiece on the beveled end of the tube and adjust the beveled end from the base of the slit until the organ pipe responds with a clear solid tone.
