Richard, Below is an excerpt from the site you provided. Thanks. After reading it, and the rest of the info on the site, it seemed to me that this Subjective Tone theory (or theorem by now), would explain why unisons sound flatter (or sharper, I forget) than their respective single strings played seperately. Any thoughts? Larry Trischetta, Pocono NE Chapter, Scranton, PA From: http://sleepy.millikin.edu/~jaskill.nsm.faculty.mu/subpitch.html (John Askill, Millikin University): A facinating series of experiments were conducted by Diana Deutsch, Professor of Psychology at the University of California at San Diego and shown in the film "What is Music" (Nova, Coronet Films). In it she subjected a listener to one series of tones in the left ear and another series in the right ear. The resulting effect was a totally different series of tones, subjective tones. The same effect was produced by listening to orchestra music produced by two or more sections of an orchestra playing at the same time. In fact, pieces of subjective music have been written in which two instruments, such as flutes, play two different sequences of tones at the same time. The resulting tones being the melody, a subjective melody. In a message dated 4/6/00 11:35:51 AM Eastern Daylight Time, richardb@c2i.net writes: > Just thought I would throw this one into the mesh.
