# Confused on marking figured bass for modulating sequence

I started writing down the figured bass of an anime theme, and for a particular passage, I am confused on how to accurately write the figured bass progression. I have recreated the bare progressions excerpt below:

From what I have learned after pouring through the Internet and my old Harmony and voice leading textbook, I believe from measure (mm) 4, the key goes from g minor to the eventual D Major through the III7 as a altered common chord (with the C#). What follows in mm 5-7 is a descending sequence of 5ths that eventually ends in the D Major.

Is my analysis correct? And if so, how should I best write out the figured bass accurately?

Your chord analysis is good. Here's my version, which is fundamentally the same. The common chord you refer to is an applied dominant, labeled V/v (read: "five of (minor) five")

``````X: 1

Just know, this is a Roman numeral analysis, not figured bass. Figured bass includes only the intervals above the bass and is not explicit about the name or function of the chord.
