Close and Open Harmony

Close And Open Harmony

Close harmony is an arrangement of the notes of chords within a narrow range. It is different from open harmony or voicing in that it uses each part on the closest harmonizing note (such as - C4, E4, G4), while the open voicing uses a broader pitch array (like - C3, G3, E4) expanding the harmonic range past the octave. Close harmony or voicing can refer to both instrumental and vocal arrangements. It can follow the standard voice-leading rules of classical harmony, as in string quartets or Bach's Chorales, or proceed in parallel motion with the melody in 3rds or 6ths.

Impressionist composers like Claude Debussy and Maurice Ravel often used close harmony in their works and other intervals, such as 7ths, 9ths, and 11ths may be used, since the chords have 4 or more notes and the harmonies are more complex. In jazz, this influence is reflected in George Gershwin's work.

Famous quotes containing the words close, open and/or harmony:

    “That was always the difference between Muhammad Ali and the rest of us. He came, he saw, and if he didn’t entirely conquer—he came as close as anybody we are likely to see in the lifetime of this doomed generation.”
    —Hunter S. Thompson (b. 1939)

    “A soul that makes virtue its companion is like an over-flowing well, for it is clean and pellucid, sweet and wholesome, open to all, rich, blameless and indestructible.”
    —Epictetus (c. 50–120)

    “Even the utmost goodwill and harmony and practical kindness are not sufficient for Friendship, for Friends do not live in harmony merely, as some say, but in melody. We do not wish for Friends to feed and clothe our bodies,—neighbors are kind enough for that,—but to do the like office to our spirits. For this few are rich enough, however well disposed they may be.”
    —Henry David Thoreau (1817–1862)
