He ceased; but still their trembling ears retained
The deep vibrations of his witching song.

Canto I, Stanza 20.James Thomson
» James Thomson - all quotes »
This is the song of the men who have no place, played by a man who has never had a place, and can therefore play it. Listen to it. You know this song, remember? This is the song you close your ears to every night, so you can sleep. This is the song you drink five martinis every evening not to hear. This is the song of the Great Loneliness, that creeps in the desert wind and dehydrates the soul. This is the song you'll listen to on the day you die. When you lay there in bed and sweat it out, you know that all the doctors and nurses and weeping friends don't mean a thing and can't help you any, can't save you one small bitter taste of it, because you are the one that's dying and not them; when you wait for it to come and know the sleep will not evade it and martinis will not put it off and conversation will not circumvent it and hobbies will not help you to escape it; then you will hear this song and remembering, recognize it. This song is Reality. Remember? Surely you remember?
James Jones
A light broke in upon my brain, —
It was the carol of a bird;
It ceased, and then it came again,
The sweetest song ear ever heard.Lord Byron
I saw how all the trembling ages past,
Moulded to her by deep and deeper breath,
Neared to the hour when Beauty breathes her last
And knows herself in death.George William Russell
Sound is defined as the result of a succession of regular and periodic vibrations. Noise is instead caused by motions that are irregular, as much in time as in intensity. 'A musical sensation,' says Helmholtz 'appears to the ear as a perfectly stable, uniform, and invariable sound.' But the quality of continuity that sound has with respect to noise, which seems instead fragmentary and irregular, is not an element sufficient to make a sharp distinction betweens sound and noise. We know that the production of sound requires not only that a body vibrate regularly but also thta these vibrations persist in the auditory nerve until the following vibration has arrived, so that the periodic vibrations blend to form a continous musical sound. At least sixteen vibrations per second are needed for this. Now, if I succeed in producing a noise with this speed. I will get a sound made up of the totality of so many noises--or better, noise whose successive repetitions will be sufficiently rapid to give a sensation of continuity like that of sound.
Luigi Russolo
It now remains that we find the amount of time of descent through the channel. This we shall obtain from the marvelous property of the pendulum, which is that it makes all its vibrations, large or small, in equal times. This requires, once and for all, that two or three or four patient and curious friends, having noted a fixed star that stands against some fixed marker, taking a pendulum of any length, shall go counting its vibrations during the whole time of return of the fixed star to its original point, and this will be the number of vibrations in 24 hours. From the number of these we can find the number of vibrations of any other pendulums, longer or shorter, at will, so that if for example those counted by us in 24 hours were 234,567, then taking another shorter pendulum with which one counts 800 vibrations while another counts 150 of the longer pendulum, we already have, by the golden rule, the number of vibrations for the whole time of 24 hours; and if we want to know the time of descent through the channel, we can easily find not only the minutes, seconds, and sixtieths of seconds, but beyond that as we please. It is true that we can pass a more exact measure by having observed the flow of water through a thin passage, for by collecting this and having weighed what passes in one minute, for example, then by weighing what passes in the time of descent through the channel we can find the most exact measure and quantity of this time, especially by making use of a balance so precise as to weigh one sixtieth of a grain.
