La música cristiana es de origen judío: la liturgia musical de la sinagoga, en particular el canto psalmódico de los judíos como unidad poética musical, fue un legado preciado transmitido del Israel antiguo al cristianismo primitivo, como forma de manifestar tanto a nivel personal como comunitario las creencias religiosas y la fe en Dios.
I am sitting in a room different from the one you are in
now. I am recording the sound of my speaking voice and I am
going to play it back into the room again and again until
the resonant frequencies of the room reinforce themselves
so that any semblance of my speech, with perhaps the
exception of r-r-r-rhythm, is destroyed. What you will
hear, then, are the natural resonant frequencies of the
room articulated by speech. I regard this activity nnnnnot
so much as a demonstration of a physical fact, but more as
a way to s-s-smooth out any irregularities my speech might
have.
