Half-diminished Seventh Chord

In music theory, the half-diminished seventh chord, also known as a half-diminished chord or a minor seventh flat five (m7♭5), is created by taking the root, minor third, diminished fifth and minor seventh (1, ♭3, ♭5 and ♭7) of any major scale; for example, C half-diminished is (C E♭ G♭ B♭). Its consecutive intervals are minor 3rd, minor 3rd, major 3rd. In diatonic harmony, the half-diminished chord naturally occurs on the 7th scale degree (for example, Bø7) in C major). By the same virtue, it also occurs on the second degree of natural minor (e.g. Dm7 (♭5) in C minor). It occurs as a leading-tone seventh chord in major and can be represented by the integer notation {0, 3, 6, 10}. It has been described as a "considerable instability".

Famous quotes containing the words chord and/or seventh:

    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)

    Tired,
    she looked up the path
    her lover would take
    as far as her eyes could see.
    On the roads,
    traffic ceased
    at the end of day
    as night slid over the sky.
    The traveller’s pained wife
    took a single step towards home,
    said, “Could he not have come at this instant?”
    and quickly craning her neck around,
    looked up the path again.
    Amaru (c. seventh century A.D.)
