440hz: the universal frequency of a traffic jam

I am going to propose an experiment,
the results of which may be astounding
the experiment can be performed using only
household items
do not proceed if you
have a heart condition
do not proceed if you
are experiencing a high tides
do not expect that you
will not be held accountable for your actions
the experiment requires of you
one cheap acoustic guitar
tuned accordingly
a bass guitar would do
the experiment requires that you
step into the traffic
into the heavy traffic
feel the strings
the thick steel strings
strike a soft buzzing "A"
