From: Gary Morrison -------------------- Begin Original Message -------------------- Message text written by INTERNET:tuning@ella.mills.edu "Gary's observations that synthetic instrumental sounds with integer harmonic spectra are satisfactory substitutes does illustrate how other aspects of sound - particularly the envelope - may be equally or more critical to our recognition of a sound. " -------------------- End Original Message -------------------- There are plenty of really interesting examples of envelopes and other aspects of a sound producing a greater feeling of recognition than overtone structure. One that pops into mind is the ol' Rhodes electric piano. Since it uses (more or less) piano hammers to strike tuning forks, it produces a quintessentially piano-like envelope with an equally quintessentially NON-piano-like overtone structure. But even beyond that, strictly-harmonic equivalents of most orchestral intruments are far to similar with their "real" counterparts for attack transients, vibrato characteristics, or even noise characteristics, to be attributable to this phenomenon.
