OK.

Well, when you want to reuse the idea of numbering the scale steps like
Förster but with different semantics then circling seems like a natural
choice.

\degree is definitely too generic and has more non-musical than
musical associations. The combination with "bass" seems to be good but
excludes the idea of numbering the melody too (which I didn't know,
honestly, but is something our package should cover as well). This
brings me back do "scale".
What do our native speaking friends think, how should one name the
numbers indicating certain positions in a scale?
\scaleDegree\scaleStepsomething different?

Making all this configurable to accomodate different schools/dialects
as well as personal preference and overall document layout will be
built in the foundation of the package. Actually this is why I have
implemented the property set functionality.
The property set for harmonic functions (so far) includes:
\definePropertySet analysis.harmony.functional#`((double-letter-offset
,number-pair? ,(cons 0.37 -0.37)) (number-size ,number? 0) (arrow-
width ,number? 1.5) (arrow-Y-offset ,number? 0) (arrow-thickness
,number? 2) (arrow-head-gap ,number? 0) (arrow-head-filled
,boolean? #f) )
I've only begun so that just gives a glimpse (I wanted to use it to
show the property set behaviour). You can configure the offset between
the letters of double functions ("DD") to change appearance or
accomodate different text fonts, the relative size of the numbers, and
various aspects of an arrow to indicate intermediate functions
("Zwischendominanten").
There will be lots of properties to configure, and presets to easily
reuse settings.
With regard to the circled numbers I didn't think of the inverted ones,
but there will be various options:
* Circled, without circle
* (Should be extensible to have other shapes if someone wants them)
* Regular document font, Notation font numbers, arbitrary font
* Dotted (Johannes Menke says, "1." "2." lends itself to spoken
language)
* Direction indicated by arrows
* Accidentals before/after the number, inside/outside the circle
* positioning details
* more?

So right now we're at
\loadModule analysis.harmony.functional\loadModule
analysis.harmony.roman-numerals\loadModule analysis.harmony.scale-
degrees
\harmonicFunction\romanNumeral\scaleDegree
