Famous quotes containing the words altered and/or chord:

    The movies were my textbooks for everything else in the world. When it wasn’t, I altered it. If I saw a college, I would see only cheerleaders or blonds. If I saw New York City, I would want to go to the slums I’d seen in the movies, where the tough kids played. If I went to Chicago, I’d want to see the brawling factories and the gangsters.
    Jill Robinson (b. 1936)

    Give me the keys. I feel for the common chord again,
    Sliding by semi-tones till I sink to a minor,—yes,
    And I blunt it into a ninth, and I stand on alien ground,
    Surveying a while the heights I rolled from into the deep;
    Which, hark, I have dared and done, for my resting-place is found,
    The C Major of this life: so, now I will try to sleep.
    Robert Browning (1812–1889)
