Diminished Seventh Chord

A diminished seventh chord is a four note chord that comprises a diminished triad plus the interval of a diminished seventh (alternatively regarded enharmonically as a major sixth) above the root. Thus it is (1, ♭3, ♭5, 7), or enharmonically (1, ♭3, ♭5, 6), of any minor scale; for example, C diminished-seventh would be (C, E♭, G♭, B), or enharmonically (C, E♭, G♭, A). It occurs as a leading-tone seventh chord in harmonic minor and can be represented by the integer notation {0, 3, 6, 9}.

Because of this it can also be viewed as four notes all stacked in intervals of a minor third. The diminished seventh contains two diminished fifths, which often resolve inwards.

In most sheet music books, Cdim or C° denotes a diminished seventh chord with root C; but it may also happen, mostly in modern jazz books and some music theory literature, that Cdim or C° denotes a diminished triad chord, while Cdim7 or C°7 denotes a diminished seventh chord.

Famous quotes containing the words chord, diminished and/or seventh:

    The notes, random
    From tuning, wander into the heat
    Like a new insect chirping in the scrub,
    Untired at noon. A chord gathers and spills....
    Philip Larkin (1922–1986)

    If the poet has pursued a moral objective, he has diminished his poetic force.
    Charles Baudelaire (1821–1867)

    Grovelling,
    intimate words,
    heart-stealing flattery,
    a tight embrace
    of my thinner-than-thin body,
    violent kisses all over—
    obviously,
    getting angry is worth the risk,
    but even still,
    I’m not interested.
    My lover
    is dear to my heart,
    so how could I be like that
    on purpose?
    Amaru (c. seventh century A.D.)
