I suppose I wondered if there might be an area under/near the finger that is
partially damped - somewhere between being fully stopped and freely
vibrating - and so any modes that have peaks in that area might be reduced
in amplitude, changing the timbre if the shape of the finger pad changes.

Having said that, only energy at frequencies at the very limits of human
hearing (and above those limits) have peaks this close to their nodes (in
the millimetre scale) so as interesting a thought as it may be, it probably
just doesn't matter! :)
