I don't see a problem with your vocabulary.
In your two examples, you aren't clear.
In the "God" question, you don't mean "God", you mean a word for a deity. Why not just ask if all languages have a native word for a deity, or if there are any known examples of native languages that were well established before adding a word for a deity?
(Indeed, asking that, I imagine any introduced word would be derivative of the deity word in the contacted language. Just like many borrowed words for recent inventions like the computer.)
In the music question, you ask if you can transpose a piece on the piano into "noise". Shouldn't it be obvious that you cannot? Wouldn't noise be random notes played on the piano?
Nothing faithfully transposed and playable on the piano is going to be random notes. Logic should tell you that.
You need to be able to read what you write analytically. The only exercise I know for that is reading the works of others analytically, looking for alternative words or phrases that would get their point across more faithfully and more concisely.
That is mostly a reading exercise. Read professional, best selling authors, but intentionally NOT for entertainment, NOT to get immersed, but analytically, to understand how they get their points across concisely and accurately.
Readers should not have to work to understand what you are writing.
It is possible to be too concise, or too verbose. But think about your word choices. It is possible to be too vague, too imprecise, and if you are reaching for broad general words like "noise" or "sad" or "happy" or "pretty", you could probably be more precise in describing what you mean.
You need professional help. Specifically, professional authors, and the works they have written!
