The audience can pick up a paddle and tap one end of the pipe mouth of different lengths to listen to the sounds produced by the pipes and feel the different tones. By knocking, the air column in the tube vibrates, and then spreads to the outside of the tube, causing the air outside the tube to vibrate, forming sound waves that are transmitted to the ear to produce sound. The pitch of a wind instrument is determined by frequency, and frequency is related to tube length. The longer the tube length, the lower the frequency, and the lower the pitch, and vice versa.
