Extended Chord - Most Frequent Voicings and Expected Resolution in The Common Practice Period

Most Frequent Voicings and Expected Resolution in The Common Practice Period

When orchestrating chords that are voiced in four or fewer parts, it is important to select which notes to use so as to give the desired sonority, or effect of the intended chord. Generally, priority should be given to the third, seventh and the most extended tone, as these factors most strongly influence the quality and function of the chord. The root is never omitted from the texture. The third defines the chord's quality as major or minor. The extended note defines the quality of the extended pitch, which may be major, minor, perfect, or augmented. The seventh factor helps to define the chord as an extended chord (and not an added note chord), and also adds to the texture. Any notes which happen to be altered, such as a flatted fifth or ninth, should also be given priority. For example: in a thirteenth chord, one would play the root, third, seventh, and thirteenth, and be able to leave out the fifth, ninth, and eleventh without affecting the function of the chord. The eleventh chord is an exception to this voicing, in which the root, seventh, ninth, and eleventh are most commonly used.

In the classical practices of western music, extended chords most often have dominant function (dominant or secondary dominant), and will resolve in circle progression (down a fifth) in much the same way that V7, V7/ii, V/IV, etc. might resolve to their respective tonics. Extended chords can also be altered dominants, and the extended pitch may be altered in several ways (such as V flat 13 in a major key).

Following standard voice leading rules:

V9 – I or i

  • The third, which will also be the seventh scale degree, always resolves upward to tonic.
  • The seventh resolves downwards stepwise to the third factor of the chord of resolution.
  • The extended pitch will resolve downward.

V11 – I or i

  • The seventh resolves downwards stepwise to the third factor of the chord of resolution.
  • The ninth resolves downwards stepwise to the fifth factor of the chord of resolution.
  • The eleventh doesn't move, and becomes the root of the chord of resolution.

V13 – I or i

  • The seventh resolves downwards stepwise to the third factor of the chord of resolution.
  • The third, which will also be the seventh scale degree, always resolves upward to tonic.
  • The thirteenth, will resolve downward to the tonic, and often includes a passing tone through the ninth factor of the chord of resolution. Less often, the thirteenth may also remain the same and become the third of the chord of resolution.

An important distinction between Extended and Added chords must be made, since the added tones and extended tones are enharmonic, but differ in function. Extended chords always have at least one octave between their lowest pitch, and extended note, otherwise the extended factor would be considered an added pitch. Extended chords usually must be resolved when used in a dominant function, whereas added chords are most often textures added to a tonic.

Famous quotes containing the words frequent, expected, resolution, common, practice and/or period:

    Much more frequent in Hollywood than the emergence of Cinderella is her sudden vanishing. At our party, even in those glowing days, the clock was always striking twelve for someone at the height of greatness; and there was never a prince to fetch her back to the happy scene.
    Ben Hecht (1893–1964)

    [My father] was a lazy man. It was the days of independent incomes, and if you had an independent income you didn’t work. You weren’t expected to. I strongly suspect that my father would not have been particularly good at working anyway. He left our house in Torquay every morning and went to his club. He returned, in a cab, for lunch, and in the afternoon went back to the club, played whist all afternoon, and returned to the house in time to dress for dinner.
    Agatha Christie (1891–1976)

    It is a part of the American character to consider nothing as desperate; to surmount every difficulty by resolution and contrivance.
    Thomas Jefferson (1743–1826)

    Thus Pegasus, a nearer way to take,
    May boldly deviate from the common track.
    From vulgar bounds with brave disorder part,
    And snatch a grace beyond the reach of art,
    Which without passing through the judgment, gains
    The heart, and all its end at once attains.
    Alexander Pope (1688–1744)

    Nonwhite and working-class women, if they are ever to identify with the organized women’s movement, must see their own diverse experiences reflected in the practice and policy statements of these predominantly white middle-class groups.
    Kimberly Crenshaw (b. 1959)

    After all, the practical reason why, when the power is once in the hands of the people, a majority are permitted, and for a long period continue, to rule is not because they are most likely to be in the right, nor because this seems fairest to the minority, but because they are physically the strongest. But a government in which the majority rule in all cases cannot be based on justice, even as far as men understand it.
    Henry David Thoreau (1817–1862)
