Changing The Pitch of A Vibrating String
There are three ways to change the pitch of a vibrating string. String instruments are tuned by varying the strings' tension because adjusting length or mass per unit length is impractical. Instruments with a fingerboard are then played by adjusting the length of the vibrating portion of the strings. The following observations all apply to a string that is infinitely flexible strung between two fixed supports. Real strings have finite curvature at the bridge and nut, and the bridge, because of its motion, are not exactly nodes of vibration. Hence the following statements about proportionality are (usually rather good) approximations.

Famous quotes containing the words changing the, changing, pitch, vibrating and/or string:
“This part of being a man, changing the way we parent, happens only when we want it to. It changes because we are determined for it to change; and the motive for changing often comes out of wanting to be the kind of parent we didn’t have.”
—Augustus Y. Napier (20th century)
“Loves riddles are, that though thy heart depart,
It stayes at home, and thou with losing savest it:
But wee will have a way more liberall,
Then changing hearts, to joyne them, so wee shall
Be one, and one anothers All.”
—John Donne (1572–1631)
“I saw the Arab map.
It resembled a mare shuffling on,
dragging its history like saddlebags,
nearing its tomb and the pitch of hell.”
—Adonis [Ali Ahmed Said] (b. 1930)
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
“The Indian remarked as before, “Must have hard wood to cook moose-meat,” as if that were a maxim, and proceeded to get it. My companion cooked some in California fashion, winding a long string of the meat round a stick and slowly turning it in his hand before the fire. It was very good. But the Indian, not approving of the mode, or because he was not allowed to cook it his own way, would not taste it.”
—Henry David Thoreau (1817–1862)
