to keep in mind the sonic air space between voices / instruments while composing and arranging music.
My friend told me that this was a very high level concept, but That may be true only by how the actionable concept is approached.
Language makes the difference, I think.
a ‘simple’ singer-songwriter in a band setting does this in their own way, listening to the different parts looking out for clashing sounds / parts.
It’s hardly any different than to ramble about the literal frequencies to be used and formed. of course at a certain point it does get more complex if they’re shaping note by note with a synthesizer [or at least, at that level of control].
This is a dumb Post, like Most 😉
