I'm analyzing a fugue in G-minor (BWV 105) by Bach that starts with Gmsus4 la-re-mi-so (G-C-D-F) 1st inversion (re-mi-so-la =C-D-F-G). I wonder what the R.N. assignment will be ...

The Thorough bass notation I think is i246, yes?

Is this the same for the analysis in Roman numbers? i246?

In the 2nd example we have Dm4 (Bassnote=4=G)

In the full score we have the root chord in the accompaniment. (1st example)

enter image description here

the 2nd example is like my question asks:

G=4, then D,A,D, and even C (Alt)

  • Please add an indication of where the chord occurs in the images posted. – Aaron Feb 16 at 17:02
  • I don't know how to draw in there. It's the 1st tied note in the bass line. I thinks the question could be answered even without notation examples. e.g. V7sus4 in C: GCDF, 3rd inversion CDFG, oh sorry, it's the 1st inversion. CDFG! – Albrecht Hügli Feb 16 at 17:07

    So you're asking about the first two beats of the second measure in the image? – Aaron Feb 16 at 17:17
  • Yes, I've edited the question. (it was so confusing to inverse the simple notation: the sus4 is in the bass voice.) – Albrecht Hügli Feb 16 at 17:18

    Posting the full score changes everything. Highly recommend getting rid of the first two images, which only confuse the question. – Aaron Feb 16 at 17:51

In the second example (-ger ge-recht, vor dir wird) without accounting for the suspension I think it would be...

Gm: ...V V4/2 | i6 Dm: IV V4/2 | i6...

...the suspension is in the bass at Dm: i6

I thought the usual way to analyze it is with suspension figures above the Roman numerals...

Dm: i6

If that were given without a score, I think it might take a bit of thought to understand the meaning: a i chord, first inversion, third is in the bass, but the bass is suspended at the fourth above the root prior to dropping down to the third to give a normal 6/3 chord.

Also, I thought in other posts we have seen the figured bass part of Roman numeral analysis would take the figures for the intervals above the bass, and I think that for this example it would be...

Dm: i5/2 i6/3
