the burden of the banjo or the traps
What does the narator imply with "the burden of the banjo or the traps"
(Something like the boring uneventful rural reality that these people suffer but cannot get away from?) Why use the word banjo?
There was dancing now on the canvas in the garden; old men
pushing young girls backward in eternal graceless circles, superior
couples holding each other tortuously, fashionably, and keeping in
the corners — and a great number of single girls dancing
individualistically or relieving the orchestra for a moment of the
burden of the banjo or the traps.
