DESCRIPTION
Tap the horizontal rods on the ends with the wooden hammer to produce longitudinal waves.  The chimes range in pitch from about 5 to 20 kHz and can be used to determine the upper limit of one's range of hearing.

A mic and scope can be used to show that the shorter tubes produce sound.

The chimes can also be used to demonstrate the dependence of pitch on length.
