With the words of Maynard James Keenan

In general art is that release caused by the friction of life.

That is the way I approach music.

I look around and see how things are in harmony

and look to the thing that are out of balance

and try to tell that story.

I am drawn to the friction.

A violin is a piece of wood that has been manipulated out of its natural shape

and twisted and bent and dried

and you take the strings

and stretch them across

very tense

very stressful

and then you take a bow

that is very straight and tight

and you drag it across with the friction

and the resulting sound

that release is the art

that is the story.
