Silence is disturbing because it is the wavelength of the soul. If we leave no space in our music, then we rob the sound we make of defining context...It’s almost as if we’re afraid of leaving space. Great music is as often about the space between the notes as it is about the notes themselves...What I’m trying to say here is that if I’m ever asked if I’m religious, I always reply, "Yes, I’m a devout musician." Music puts me in touch with something beyond intellect, something otherworldly, something sacred.
The song of a river ordinarily means the tune that waters play on rock, root, and rapid....This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. To hear even a few notes of it you must first live here for a long time, and you must know the speech of hills and rivers. Then on a still night, when the campfire is low and the Pleiades have climbed over the rimrocks, sit quietly and listen for a wolf to howl, and think of everything you have seen and tried to understand. Then you may hear it--a vast pulsing harmony--its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.
~ Aldo Leopold, "Song of the Gavilan" in A SAND COUNTY ALMANAC
