Paint is not in the fingers of the painter
Clay is not in the fingers of the sculptor
Fire is not in the breath of the flame throwing artist
And TONE is NOT in the fingers of the guitar player
I give up...
You give up because you are inaccurately applying art metaphors.
For example, paint is not in the fingers, but the stroke and application of the paint certainly is in the fingers manipulating the brush or knife - the latter skills of the fingers are what we recognize when discussing a skilled painter rather than which titanium white he decided to use.
Clay medium is not in the fingers of the sculptor, but certainly the manipulation, pressure, and smoothing gestures which shape the clay are in the fingers and hands of the sculptor. Those efforts are what we are talking about when discussing a sculptor's output more so than the quantity of rough clay he acquired.
Etc.
