e/Tritone paradox

Information
has gloss	eng: The tritone paradox is an auditory illusion in which a sequentially played pair of Shepard tones separated by an interval of a tritone, or half octave, is heard as ascending by some people and as descending by others. Different populations tend to favor one of a limited set of different spots around the chromatic circle as central to the set of "higher" tones. The tritone paradox was first reported by psychology of music researcher Diana Deutsch in 1986.
