You dont get what i spoke about it seems...
When you speak are you conscious of the complex mechanisms behind syntax and semantic ? Not at all, we learned it without even knowing what we do...
It is the same for the musical time, which is born from our complex response to society and to Nature from the body members (rythm) and from the throat/mouth (timbre and tonality)...
Then this "musical sophistication" occurred from the beginning...But it is now that we get this sophistication consciously understood...
Ancient language are not less complex than english... it is the opposite...
And Einstein concept of time or Newton concept of time has nothing to do with "musical time" not measured by the watch, and if so is being denatured and lost...It must be felt not counted...
All of this musical sophistication couldn’t have occurred at once. Certain things must have happened first, then others, then others. Early Homos sapiens probably didn’t have a concept of time beyond the sun setting and rising.
