Diatonic and Chromatic - Chords

Chords

Diatonic chords are generally understood as those that are built using only notes from the same diatonic scale; all other chords are considered chromatic. However, given the ambiguity of diatonic scale, this definition, too, is ambiguous. And for some theorists, chords are only ever diatonic in a relative sense: the augmented triad E♭–G–B♮ is diatonic "to" or "in" C minor. On this understanding, the diminished seventh chord built on the leading note is accepted as diatonic in minor keys. If the strictest understanding of the term diatonic scale is adhered to - whereby only transposed 'white note scales' are considered diatonic - even a major triad on the dominant scale degree in C minor (G–B♮–D) would be chromatic or altered in C minor. Some writers use the phrase "diatonic to" as a synonym for "belonging to". Therefore a chord can be said to be diatonic if its notes belong to the underlying diatonic scale of the key.

Famous quotes containing the word chords:

    I love power. But it is as an artist that I love it. I love it as a musician loves his violin, to draw out its sounds and chords and harmonies.
    Napoleon Bonaparte (1769–1821)

    Love took up the glass of Time, and turned it in his glowing hands;
    Every moment, lightly shaken, ran itself in golden sands.
    Love took up the harp of Life, and smote on all the chords with
    might;
    Smote the chord of Self, that, trembling, passed in music out of sight.
    Alfred Tennyson (1809–1892)

    To be a poet is to have a soul so quick to discern, that no shade of quality escapes it, and so quick to feel, that discernment is but a hand playing with finely-ordered variety on the chords of emotion—a soul in which knowledge passes instantaneously into feeling, and feeling flashes back as a new organ of knowledge. One may have that condition by fits only.
    George Eliot [Mary Ann (or Marian)
