Im curious about educated responses here as well. Some little factoids:
-highest string of a violin, unfingered, is 660hz. But it's uppermost range is a bit under 3.5khz (IMO, very treble!) and this does NOT include extended techniques such as artificial harmonics
-lowest unfingered note on a guitar is just a shade over 80hz. A 6-string electric guitar with 24 frets goes up to 1320hz. Again, not including extended techniques, such as bends, whammy bars, bending neck, art harmonics, electronic devices.
-Bass vocalists sing below 80hz. However, these same bass vocalists will sing up to 330hz.
-soprano will sing between (roughly) 250hz to 1.2khz.
-lowest note on a double bass is not far from 3 octaves below middle C. However, its uppermost range gets to above middle C!
The above are the "normal" ranges. Various individuals can and will go beyond limits, whether below or above. Most of my math above is using 440hz as concert A, and applying "perfect intervals" when my math-challenged brain is at work. Untempered, if you will.
Hm, well looking at the attached graph, I guess my efforts are wasted. lol.
It seems the most difficult classifications are from the mids-on-up. I guess I would consider everything above 800-1000hz as treble already. (It's already an octave above Concert A, or 440 hz). It's difficult to accomodate both the audiophile's and musician's perspective, at least it seems to me. For instance, I personally think the 24th fret is pretty treble! But with the attempted tries above, it's only "Mid"!
This is a good idea though to shed light on this stuff....
