diminished seventh chord
The diminished seventh chord is commonly used in the harmony of both Western classical music and also in jazz and popular music of the twentieth and twenty-first centuries. Classical composers of the eighteenth and nineteenth centuries imaginatively exploited the chord's dramatic and expressive potential. (See below).
==Definition==
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 .
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.〔Benward & Saker (2003). ''Music: In Theory and Practice, Vol. I'', p.219. Seventh Edition. ISBN 978-0-07-294262-0.〕
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° or Cm(♭5) denotes a diminished triad, while Cdim7 or C°7 or Cm6(♭5) denotes a diminished seventh chord.
