Shepard tones
Shepard tone paradox (after its inventor, Roger Shepard), one's perception is that each note in a forever on going series of notes is higher in pitch than the preceding note.

The tones used to create the tritone paradox were synthesized by Diana Deutsch at the University of California - San Diego. The tones used are similar to those created by Roger Shepard in that they are specially designed complex tones that consist of ocatve related sinewave components. Shepard tones consist of 10 components (octaves) and are presented through a Gaussian-shaped spectral filter.

The tones used in the tritone paradox have 6 components (octaves) and are presented through a bell-shaped spectral envelope. The filtering results in the frequency components being attenuated about the centre frequency. These Deutsch tones are perceptually similar to Shepard tones, although to date, there has been no systematic investigation of perceptual effects arising from the differences between the two types of tones.

Do you remember the brief discussion of auditory stream formation theory?
