Chord #ivd7, Resolution ?? Options

[Jungfrauenregalbass]

if it was the inversion then you would write it #iv7d.

I'm okay now thanks J. The d means the third inversion and Sue confirmed a couple of posts ago that p79 in HIP states the o is in fact omitted.

But then this diminished seventh chord rarely appears in third inversion. It would have to resolve to the second inversion of the dominant triad (extremely unlikely) or the second inversion of the dominant seventh chord (plausible but uncommon).

I don't think it is diminished.
as theres no o it cant be both diminished and third inversion, can it?

#IVd7

The chord under discussion is on p84 of Harmony in Practice : F sharp, A natural, C, E flat - a root position diminished chord based on an altered IVth note.

I don't understand if 'd' is the inversion or if its diminished.

I've just looked in the Butterworth book at the explanation on p84 and it says the little d7 means it's diminshed - not an o in sight! (IMG:style_emoticons/default/ohmy.gif) (IMG:style_emoticons/default/ohmy.gif) Bit confused myself now, especially as on page xiv Chord Labelling it says the o is used for any chord which has a diminished 5th and the letters a b c d show inversions. Then there is a nice #ivo at the top of page xv.

Why is p84 wihtout an o?

what is an o?

so Its not an inversion? (IMG:style_emoticons/default/wacko.gif)
you just resolve into a G major or minor chord.

Yes that's right - the d refers to diminished 7th - it is clearer if you see it in the book where the d7 is written in smaller type as a superscript.

I was getting thoroughly confused too, so I went and had a look in H in P. From what I can make out you use the little (superscript) "o" for a diminished triad (3 notes built up on minor 3rds with the bottom and top notes a diminished 5th), and use the (superscript) "d7" for a diminished 7th chord (4 notes built up on minor thirds with the 7th and the 5th being diminished intervals)

so to show its an inversion you need to write #ivd7d? (IMG:style_emoticons/default/wacko.gif)

why not just have an o and keep things simple?

[SueHM]

o is for diminished 5th
d7 for diminished (5th and) 7th
d after the chord name for a 3rd inversion

What could posibly be confusing about that?! (IMG:style_emoticons/default/wacko.gif)

Now step away from the theory book.....!

I don't understand why AB don't make the authors of its theory textbooks adopt notation that is used elsewhere in the English-speaking world.

For example, it'd be so much clearer to label inversions of triads with numbers 6 and 6/4, and for the seventh chords, 7, 6/5, 4/3 and 4/2.

I think b,c and d are fine for the inversions and o for diminished.

there is no need for another d for diminished 5ths and 7ths.
