How to write dim7 chord inversions in roman numerals?

How to write dim7 chord inversions in roman numerals?

Hello!

If you're familiar with Barry Harris 6th diminished scale, it is preferrable to think in this category (but the question is more general). I want to notate, for example, simple progression: Bdim7 – C6 – Bdim7/D – C6/E – Bdim7/F – C6/G – Bdim7/Ab – C6/A – Bdim7 – C6

How should I write abstract names for these inversions? I want the diminished 7th chord to stay on the 7th scale degree: viio7.

Given this, how it is better to write the function of 'Bdim7/D' chord?

viio7/2 ? Maybe it is confusing

The only other option I can think of is to just write it like iio7. It is more clear but I feel like the function starts getting lost here.

* * *

The image is the example I'm writing. I wrote these changes like: viio7 | I6 viio7/IV IV6 viio7/2 I6/3

I have no formal training so I guess this might look cringey :)

The other option is just go all-ahead into the abstraction of the roman numerls and write: viio7 – I6 – viio7 – I6 – viio7 – I6 – etc....

or viio7/IV – IV6

Thanks for your responds!

How do you notate notes of the harmonic 13 chord?

Which names and accidentals would you use? I'm lost a bit.

If I write:

C E G Bdb D Ft Ad

Will it suit temperaments like 31 EDO only? What about JI? I know about 4:5:6:7:9:11:13 but here I want specific names.

Should I write cents in every note compared to 12-TET? Like:

C E(-14c) G(+2c) Bb(-31c)

And finally, should I use saggital notation for JI here? Does it have like sesquiflats? What shoul I do for everyone to understand me?

Thanks for your answers!
