No. 50: Mar-Apr 1987
No wonder music critics often disagree, they do not necessarily hear the same thing, even when sitting side by side in the same concert hall!
"The discovery, made by psychologist Diana Deutsch of the University of California at San Diego, concerns pairs of tones that are a half octave apart. When one tone of a pair, followed by a second, is played, some listeners hear the second tone as higher in pitch than the first. Other people, hearing the same tones, insist that the second tone appears to be lower in pitch."
Other differences in perception also exist in the world of music.
