Stupid question, but is it in caps or small i.e. II+ or ii+

I would do 5+
3
As that is how it's standardly notated.

The US system would use capitalisation, 'II+' because it has the major third. (A) European system, and the one I prefer, uses normal 'ii' with figured bass next to it: Image.

Never heard of using Arabic Numerals, only Roman.

It would be Arabic numerals in figured bass. 8)

What a pity that this example is actually in error, since a ii+ chord in C over an F sharp would be figured as 6/3 according to the rules of figured bass (i.e. first inversion), not as 6/#! :roll:

The # is in regard to a #3. The 3rd is generally not shown in figured bass; root chords do not display the 3, and 1st inversion chords are displayed as a 6 (without the 3). If the # was in relation to the 6th, it would be either before or after that figure, not below it. Also, if we where displaying all fugures it would be:
6
#3

or

6
3#

not

6
3

as that would merely make a ii chord in C major, a major chord instead of minor.
It would be Arabic numerals in figured bass.
Ahh, I re-read it. I thought you were substituting the Roman, please ignore that!

Hi Yagan,

Ah, I didn't actually read the title of the thread (the word augmented). You are quite correct, the 3rd over the F# should be raised for the chord to be augmented. My bad :)
