So we talked about all the diatonic C Major chords except for ''B Diminished''. Time to cover it now.
<u>Diminished chords Chords</u> are comprised of a root, its minor third, and its diminished 5th. The distance between the minor third and the diminished fifth is another minor third, so the chord is composed of 2 minor thirds and 1 diminished fifth (and their inverses).

B dim is diatonic to the key of C Major, using its 7th scale degree as the root note. Thus, it is called the <u>vii </u> or <u>vii° chord</u>. The ° indicates diminished, but you have to be careful - we are dealing with the diminished triad here, not the diminished seventh. The Diminished 7th chord has two variations - half and full. Half is indicated with a slash through the ° symbol. ''Where the {{dim}} symbol cannot be made, such as on a standard keyboard, or to avoid ambiguity, you can use "dim" (ex. Bdim) to indicate the diminished quality of the chord.''
The vii chord is called the <u>Leading Chord</u>. Harmonically, it has a ''dominant '' function.

Now that we know the vii {{dim}} chord, we can play the full circle progression in the key of C Major.
