Close up, much too, ivory’s surface like most
surfaces is nothing smooth. To the touch
in all particulars it’s what the fresh
strawberry is to the tongue, cilia
bending at the buds after lunch. Specialists
in friction will tell you what pianists

with all of Mozart’s sonatas in their heads 
and hands will—except the ones who never 
notice—that plastic slips and ivory catches,
the catch being what you want. To the touch:
everything is what it is to the touch,
algebra included, according to experts.
