Famous quotes containing the words frequency and/or bands:
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“Nearly all the bands are mustered out of service; ours therefore is a novelty. We marched a few miles yesterday on a road where troops have not before marched. It was funny to see the children. I saw our boys running after the music in many a group of clean, bright-looking, excited little fellows.”
—Rutherford Birchard Hayes (1822–1893)
