In jazz, the diminished seventh chord is often based on the ♭ scale degree (the flat mediant) and acts as a passing chord between the mediant triad (or first-inversion tonic triad) and the supertonic triad: in C major, this would be the chord progression E minor – E♭ diminished – D minor. In most sheet music books, the notation Cdim or Co 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 Co denotes a diminished triad (more commonly denoted Cm♭5), while Cdim7 or Co7 in these books denotes a diminished seventh chord (corresponding to Cm6♭5). The placid conclusion of the andante movement is interrupted first by a slowly rolled diminished seventh arpeggio played pianissimo, followed by the same chord played an octave above in a sharp, stabbing fortissimo.[17]. The dead man’s statue comes to life and takes the Don down to Hell in one of the most chilling episodes in the entire operatic repertoire (Listen): In the early years of the 19th century, composers used the diminished seventh with increasing frequency. Since the chord may be enharmonically written in four different ways without changing the sound, we may multiply the above by four, making a total of forty-eight possible interpretations. 日本語では「減七の和音」と呼ばれるこのコードの特徴は、４つの音がすべて減３度間隔で積み重なっている点にあります。, ２つのトライ・トーン（３全音）が形成されているので、極めて不安定な響きを生じます。, ディミニッシュ・セブンスはその構成音で分類すると、３種類に集約されます。つまり、譜例の「Cdim7」の場合ですと、C音だけでなくE♭、G♭、B♭♭のすべてがルートになるということです。. Because the diminished chord and its inversions have the same shape, there are only 5 shapes to learn. [6] The dominant ninth theory was questioned by Heinrich Schenker. Percy Goetschius calls it the "enharmonic chord. The intervals that compose the C Diminished Seventh chord are Root, Minor Third, diminished Fifth, and Diminished Seventh. Perhaps the clearest instance of the diminished seventh’s power to evoke mystery and terror can be found in the passage linking the two final movements of Beethoven’s Appassionata Sonata, Op. But even when its not being used as a replacement for the V, diminished chords are capable of adding an entirely new dimension to any chord progression. The diminished chord is a triad with two minor thirds, or a minor third and a diminished fifth, which gives us an unstable chord, which needs to be resolved to another chord.

These notes occur naturally in the harmonic minor scale. A viio7 chord in the minor key (for example, in C minor, B♮–D–F–A♭) occurs naturally in the harmonic minor scale and is equivalent to the dominant 7♭9 chord (G–B–D–F–A♭) without its root.

The diminished seventh chord occurs as a leading-tone seventh chord in the harmonic minor scale. Diminished chords, like major and minor chords, occur naturally in every key, and each key has only one diminished chord. François-Joseph Fétis tuned the chord 10:12:14:17 (17-limit tuning).[3].

In the key of C, this is F♯dim7. The diminished seventh chord is a seventh chord composed of a root note, together with a minor third, a diminished fifth, and a diminished seventh above the root: (1, ♭3, ♭5, 7).

Another common usage of ♯ivo7 is often found in Gospel music and jazz progressions such as in the song "I Got Rhythm": One variant of the supertonic seventh chord is the supertonic diminished seventh[10] with the raised supertonic, which is enharmonically equivalence to the lowered third through (in C: D♯ = E♭).
