The pause - that impressive silence, that eloquent silence, that geometrically progressive silence which often achieves a desired effect where no combination of words, howsoever felicitous, could accomplish it.
Words move, music moves Only in time; but that which is only living Can only die. Words, after speech, reach Into the silence. Only by the form, the pattern, Can words or music reach The stillness.
Now the Sirens have a still more fatal weapon than their song, namely their silence... someone might possibly have escaped from their singing; but from their silence, certainly never.
