It makes sence to try out, not listening to music while making art. Sometimes, when the artwork requires more gruntwork, it's nice to get in a constant groove/rythm. But when you need to let multiple things sink in (things like shape, perspective and placement), those things can sink in, at different speeds and intensity.
And as a teacher you want to take record of your student's progress in their neutral rythm (not the rythm of whatever songs you listen to each lesson).
Though it's a bitch, sometimes, the world needs to shut up around you, to listen to the more silent things (instead of only the silent things in your mind when you sleep).
But the social things totally make sence. Even if you take away sound, people can still enter your vision to let you know they need something from you (like a normal way to approach people). Or let people use their other sences, as long as you do it respectfully. And I suppose, that the whole respect mumbo jumbo is the issue.
But all in all, sublimely illustrated and narrated. Gives a good point of view with some solid points (that a lot of people can take usefull things from).
Thank you & well done!
