Module figuredbass 

Figured bass: the numbers written under a bass note. Figured bass: the numbers written under a bass note, and what they mean.

A column of figures says how far above the bass each note of the chord stands, and an accidental beside a number says how that note is spelled. Most of a column is left out in practice — a bare 7 means a seventh chord in root position, fifth and third and all — so a column is read in two forms: as written, and expanded to every note it stands for.

This is the port of music21’s figuredBass.notation, and it is what crate::roman::RomanNumeral reads its own digits with.
