What does a diminished 7 resolve to?

Diminished sevenths always resolve to a chord a semitone above their root so in the example below the F# diminished seventh resolves to ii (G minor) and the B diminished seventh eventually resolves to C (with a 6/4 in between).

Why is it called a diminished 7th?

A diminished 7th chord is contructed by piling minor thirds one on top of another, which is why it has to be Bbb and not A, and therefore the two outer notes form a diminished 7th interval, which is why the chord is called a diminished 7th chord.

What is a diminished interval?

A diminished interval has one less half step than a perfect interval. A diminished interval has one less semitone than a perfect interval. Since C to G is a perfect fifth (7 half steps), C to Gb would be a diminished fifth (6 half steps).

What does diminished mean in music?

What is a diminished chord? A diminished chord is a type of chord that contains a minor 3rd (three half steps above the root) coupled with a diminished 5th (six half steps above the root). It has a distinctive timbre: tense, dark, and unstable sounding. And without context, diminished chords may sound off-putting.

How do you make a diminished 7 chord?

Dim7 chords are symmetrical, they are based on an equal division of the octave into four minor third intervals. That means there are four different diminished chords in one position. For example, C diminished 7th contains four notes : C, Eb, Gb and A. Each note is separated by three semitones (minor thirds).

What's the difference between a minor 7th and a diminished 7th?

The half diminished chord (m7b5) has a minor seventh (7) - it's a m7 chord wth a flat five (b5). The diminished chord has a diminished seventh (dim7, °7). The minor 7th is again decreased by a semitone and hence is equivalent to a sixth (6) - only the theoretical approach is different.

What is the difference between a dominant 7th and a diminished 7th?

Referring to the dominant 7th chord itself, the 3rd rises by a semitone and the 7th falls by a semitone when we move from dominant 7th to tonic. This is an example of semitonal pull. A diminished 7th is a chord built upon consecutive minor 3rds, and tends to be used to create tension in a phrase.

What is the difference between half diminished and fully diminished?

The fully diminished seventh can be indicated as dim7 or with the ° symbol.
