I quite agree that speculation is my method when simply puzzling it out consistently doesn't work.
I don't know why I couldn't puzzle this one out using obvious factors of pure tone and lowest tone.
I arrived at my answer by trying to whistle tones and "A" over middle "C" was the...
Best answer yet: Tuning note "A" is lowest pure tone average human is able to produce
whether by actually whistling, which most people can do, or by trained voice using "whistle register," the lowest comfortable pure tone is A over Middle C.
Pure tone is common denominator between...
by calculating Earth circumference divided by any time unit, speed of sound is equal to apparent ground speed of sun at latitude 42.5 degrees
that seems to apply for all notes equally, so no direct conclusion seems applicable to tuning notes or any other.
speed of sound = 1125 feet per...
thanks for the responses.
No overall criteria were suggested for choosing the tuning note and that note's cps;
yet it doesn't seem the result of a mysterious combination of factors, only accidentally arrived at, or random, or so many subjective inputs so varied and so complex to be...
Apparently extensive music theory of European, Hellenistic and ancient world is beyond my current depth. However, it seems reasonable to expect that western musical notes have a substantive physical basis in addition to relative consistency and obvious physical parameters.
Obvious...
