In figured bass, a note is written on the staff over which the chord will be
built.

If there is no figure, it implies 5/3 (and we may see 5, 3, or 5/3) and a
3rd and 5th are added above the note (root position).

If the figure is 6 or 6/3, a 3rd and 6th are added (1st inversion).

If the figure is 6/4, a 4th and 6th are added (2nd inversion - there's no
"abbreviation" for this one - the full figure must be included to avoid
confusion with other figures).

So if one writes out the bass note with a name, this is very similar to
modern chord notation.

In Roman Numeral analysis, RN append as:
 
I (RP)
I6 (6 superscript, 1st inv.)
I6/4 (6 super, 4 sub, so stacked, 2nd inv.).
 
For 4 note chords,
V7 (RP)
V6/5 (1st)
V4/3 (2nd)
V4/2 (3rd) - sometimes just V2 (but that's an homage to Piston as far as I 
can tell).

So this writes out the position of the root as a number in the scale, plus
the numbers in thoroughbass, if one assumes that the chord should be built
up by thirds.

There's some advantage to this system in that it shows a lot more clearly 
what's happening with NCTs, but can quickly get to be too much information - 
it basically becomes another form of notation which, for analysis, might be 
counter to what one wants to get at.

It seems that the idea is to write out what is the harmonic function, and
then add what one is used to reading in figured bass to identify the
inversion.

If one should generalize to modern music using more complex chords, I
think it would be best to write out the chord as in thoroughbass with a
note name or numbers identifying the lowest note in the given position,
plus the perceived root. I am not sure though exactly what notation to
use.

The point is, and I'm sure Steve will correct me if I'm wrong, that in an analysis of any music from the CPP the description of a I chord with added 6th would be seen as some sort of a mistake because those composers would never have written anything that could be correctly analyzed that way. ... for inversions attach the numbers one gets in the thoroughbass notation. ...
