Music and Columns of Air
|
Introduction |
| The
sound of an vibrating object can be enhanced by causing an air column
to vibrate. The varying lengths of the air columns are related to
the pitch or frequency of the sound that is generated.
Playing an
organ with varying pipe lengths shows that the high frequency or
short wavelength sounds use the short pipes. On the other hand,
the long pipes are used to generate the low frequency or long wavelength
sounds. Other wind instruments use valves or slides to alter the
length of the air columns. |
