A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played it creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower. (wiki)

The Shepard tone supposedly elicits a similar response to most folks who listen to it, that it is foreboding, possibly depressing, even scary.
