# How would you write an inversion of a suspended chord with functional chord symbols? [duplicate]

Ex.

Would the second chord be written as I7 - 6 or I62 - 1?

• Which do you think is correct? Dec 7, 2021 at 22:44
• @AndrewChin My first idea was to label it I7 - 6, but I7 is also a dominant 7th chord. The other option doesn't show the intervals between the upper 3 notes and the bass. Dec 7, 2021 at 23:38
• Technically, a I can’t be a dominant 7th, but I’m nitpicking. Aaron’s right, this has been covered before, though that other Q/A is a bit confusing. I’m not sure I agree with the accepted answer that it’s “more common” to just not show the suspension in the roman numerals, but check out the Aldwell & Schachter page it links to. That’s what I’m used to —that is to say, yes, I7—6. Dec 8, 2021 at 1:23
• If it were in root position the figured bass would more idiomatically be written 9-8 rather than 2-1. Dec 8, 2021 at 11:56

Your second option - `2-1` - looks like scale degree numbers, but you don't want to use those.
The bass is `E` and the suspended note above is a `D` which is a seventh above the bass. So, the chord is `I`, but given the bass the intervals above the bass as `3/6/7`. So, it's `I3/6/7`.
FWIW, the chord is not a seventh chord, and of course, it is not a ninth chord. The point of the suspension figure is to recognize the `D` is not a chord tone. One way to analyze this passage is to just write `V4/2 I6` below for the chords, and for the suspension figure, a melodic aspect, just put `sus`, or `9-8` above the `D` in the treble clef. (See @phoogs comment about `9-8` versus `2-1`.)
Personally, I think `I3/6/7` is hard to read and understand. `V4/2 I6` with `sus` or `9-8` keeps harmonic analysis symbols with chords and non-chord tone analysis separate with suspension figures.
