IMO Improvistional Theatre is the only valid example here, the other 6 IMO are silent and I will explain why:
1. Music - Done mainly in ones own head, drawing on personal experience and skill to find something which fits with what you are hearing. The process may not be silent, but the creation is.
2. Stand up comedy - The writing/creation is done by the comedian alone, then when workshopping in front of a live audience they assessing the material against the reactions, and adjusting it in their brain silently. An audience reacting is not creating anything, it is informing the creative process going on in the brain.
3. Literature has editors and friends who read drafts - again all the creation is done in silence. Feedback may be given verbally, but that informs the creation, it is not part of it.
4. Product development - This is not artistic creation. It is commerical development. The initial idea and creation is most likely done by an inventor/designer on their own in silence. It is commercial requirements which push this into the further areas of development as you suggest.
I fully accept this is a subjective opinion so I am not stating you are wrong, only how other people can have different opinions based on perspective of what creation, the creative process, and indeed silence actually is.
You must have miscounted because I cant find another 2?
How many of these have you actually observed happening? Because your assertions that they are "silent" (in the sense of the original piece) seems wildly out of line with what I've seen. You might try watching the documentary I linked to see how you're wrong about recorded music, for example. And if if your only experience of product development is that sort of top-down drudgery, I'm truly sorry, but it absolutely can be richly creative and collaborative.
> You must have miscounted because I cant find another 2?
That you're blaming your failures on me is not a good sign, so this is probably my last reply. I also mentioned improvisational music and movies. I could also add staged theater, in which much of the creative work happens in group contexts (starting with table readings, going through all of the rehearsals, and often after).
Gosh, a person on the internet has opinions on my writing! Truly a novel experience for me.
I'm sure I have a lot to learn about how to write for this audience from a person who [checks profile] joined this site last week. But that would make you a bit of an expert in both arrogance and dismissiveness, so I'll definitely give it a think.
Please refresh on the guidelines. Your comment does nothing but break them. "Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes. ...Please don't sneer" etc. If you edited out your swipes there'd be nothing left.
These all seem super arbitrary - like Product development for example, who says that commercial development isn't artistic? So if there's money involved it's not art...? What about video games, I am pretty sure a lot of people consider those to be art, and it's also a collaborative commercial creative process.
Same with music, there are plenty of jam sessions where people create music together totally improvised on the spot. I mean pretty much all of them can be done collaboratively if people felt like it, and often do.
> 1. Music - Done mainly in ones own head, drawing on personal experience and skill to find something which fits with what you are hearing. The process may not be silent, but the creation is.
You don't write music, do you? And I guess you've never been at a jam session either.
Which example? I gave 7.
