Comunque qualche esempio nel thread che ti ho citato c'è. Questo è abbastanza esplicito:
Hi there,
Another clarification occurred to me.
The "music" does not correspond to speaking. It corresponds to shared, imaginative creativity (the Exploration), along communicative space among all the participants.
Therefore my "invisibility" comment may be throwing people off the track. I am thinking of play circumstances in which the GM provides many cues not only for people to do something, but specifically what they are supposed to do.
- "You sure you wanna do that?" (pause) "You're sure?"
- More extremely, "You don't wanna do that. You don't know whether they left a booby-trap in that safe, or what."
- Glancing humorously toward "faithful" players, such that they spring into action to dissuade the active one.
None of this is playing bass. If that's what you're thinking of when you read "invisible," that's not what I mean at all. I do not mean "not accountable, or you can't prove otherwise." I mean, literally, that the GM does not determine the actions of the characters which decisively resolve the conflicts at hand. He does not write or play the song.
Here's the big therefore:
Many GMs think they play bass but in reality are playing a Moog synthesizer, permitting the players to chime in on pennywhistles. Sure, the players have "freedom" to toot their hearts out, but they can't contribute much to the communicative space in terms of presence or content.
Many GMs act as orchestral conductors, laying out the sheet music and organizing who goes when, keeping everyone all in the same song with its content all laid out.
Many GMs simply oversee a lot of cacophony, but operating "the board," which is to say, editing, increasing and decreasing volumes, rearranging the order of things, adding, sweetening, and so on.
Many GMs seem to play bass, but whenever it's time for a solo, they'll grab the instruments away and play them themselves, or stand behind the player and move his or her fingers for them.
Best,
Ron
