As a young man I acquired a book by A. N. Whitehead,
Symbolism: It's Meaning and Effect. (it's easily found free on the internet). I was for decades, intimidated by the reputation of a Great Philosopher. In other words, I assumed I was not smart enough to understand it. About 15 years I stumbled on the book and simply started to read it, and found it took some thinking, but that's all.
One of the terms Whitehead uses is "presentational immediacy." In plain English it means "our immediate perception of the contemporary external world." Or, reality as we, a living organism, experience it. Measurements are
symbols which stand it for things. Symbols can of course be quite useful. But modern scientific skeptics in a lot field use symbols as clubs to basically say: what people experience directly can't be trusted. (I suspect that some skeptics wish that they could just get rid of those pesky living organisms that mess up their clean understanding of things.)
But, back to music. Prior to the invention of electronics, all of our music, including the musical instruments humans invented, not to mention the use of the human voice in music, were invented without electronic measurements. The tubas, woodwinds, strings, tympani, sitar, gamelan-- our human direct human hearing was fine enough to create and improve all those instrument. We didn't need electronic measurements.
James Boyk in a blog, paraphrasing, once posted that, as an expert in the piano (he was the Caltech Professor of piano for many years), he is expected to be able to tell when a piano is in out out of tune, or malfunctioning, or to tell one from another or maybe even recognize a particular piano or person playing, all by ear. But the moment someone sticks a microphone into the equation, his expertise no longer has any value.
Suggested listening. Steve Guttenberg Accuracy, does it exist? In audio or recordings?

Eno: The Studio as a compositional tool
Eno gave several lectures in circa 1979 by this title. There is a poorly recorded youtube lecture by this title (voice only, no video)
Here is print version, the two examples overlap

"We've spoken of the transition from the '50s concept of music to the contemporary concept of mixing. If you listen to records from the '50s, you'll find that all the melodic information is mixed very loud - your first impression of the piece is of melody - and the rhythmic information is mixed rather quietly. The bass is indistinct, and the bass is only playing the root note of the chord in most cases, adding some resonance."
The above largely was due to the influence of the classical music world, with a large focus on melody.
