Track 1

This audio file presents three sounds in succession. In the first, you hear an example of white noise, which, because it contains so many random frequencies, represents itself to the ear as a hissing sound of indeterminate pitch. The second example is of a sine wave, a single frequency whose pitch, amplitude, and timbre are readily audible—a true musical sound. The third example uses the white noise sample already given to create a series of percussive sounds, showing that even noises can be used if they are presented in an intelligible musical context.
