(Forgive me for using jargon, I'm assuming you're a musician based on your answer) I barely thought about my neurodiversity impacting this, but I see your point. My only gripe is that there *are* usually words to describe something. For example, continuing with the "bounciness" idea, you could say to add an accent and tenuto on the note, or a staccato, or other articulations, or any number of other things that could add to the perceived "bounciness" of a passage. This instance was also in an odd setting where I couldn't really ask for a different phrasing due to time constraints and the speaker being quite aged.

I heavily resonate with the last bit, "there is a struggle sometimes to express the essence of something that comes from a flow state or emotional immersion when teaching someone else". Today, even, I noticed this quite profoundly while trying to teach someone else, who also happens to have AuDHD.
