I really just filed this note about the aesthetics of your figured bass output because I understand that you want LilyPond to be taken up because the output does not look stiff and computer-like. For practical purposes the figures are reasonably easy to play from as they are, though overall a bit far away from the notes.

Here is the same example using few scheme utilities:
--
#(use-modules (ice-9 optargs)
(lilypond markups)) ; [1] See below
#(defmacro* fig (#:rest figs)
"Figured bass as markups. Each of `figs' arguments may be
a number, a variable referencing a markup, a list of
numbers or markups (for lining text), or a (keyworded) markup
command."
`(markup (#:column ,@(map gen-figures figs
#(define (gen-figures figure)
(cond ((and (pair? figure) (keyword? (car figure)))
`(,(car figure) ,@(map gen-figures (cdr figure
((and (pair? figure) (not (null? (cdr figure
`(#:line ,@(map gen-figures figure)))
((pair? figure)
(gen-figures (car figure)))
((number? figure)
`(#:string ,(number->string figure)))
(else
figure)))
nat = \markup { \musicglyph #"accidentals-0" }
sh = \markup { \smaller \raise #0.6 \musicglyph #"accidentals-1" }
fl = \markup { \musicglyph #"accidentals--1" }
\score {
\context Voice \notes {
\clef bass
\property Voice.TextScript \set #'font-family = #'number
\property Voice.TextScript \set #'font-relative-size = #-3
\property Voice.TextScript \set #'baseline-skip = #1.4
dis4_#(fig 6)
c_#(fig 7)
d_#(fig (6 sh) (#:bracket nat))
ais_#(fig 6 5 (#:bracket 3 sh))
}
}

In effect, you are saying that you want the bass figures to behave
like texts and fingerings wrt. notes. Implementing this is possible,
and not even that difficult - but not very high on my current priority
list.
For the moment, you could use markup texts. For example:
\header
{
texidoc = "An alternate method to make bass figures is to use
markup texts."
}
\version "1.9.4"
nat = \markup { \musicglyph #"accidentals-0" }
sh = \markup { \smaller \raise #0.6 \musicglyph #"accidentals-1" }
fl = \markup { \musicglyph #"accidentals--1" }
\score {
\context Voice \notes {
\clef bass
\property Voice.TextScript \set #'font-family = #'number
\property Voice.TextScript \set #'font-relative-size = #-3
\property Voice.TextScript \set #'baseline-skip = #1.4
dis4_\markup { 6 }
c_\markup { 7 }
d_\markup { \column < { 6 \sh } \bracket { \nat } >}
ais_\markup { \column < 6 5 \bracket { 3 \sh } >}
}
}
Use << >> iso. < > for 1.8, and quote the numbers, i.e.
\column << { "6" \sh } ...

The last problem is easily fixed:

I've added this to scm/grob-description.scm
This change seems to have got lost - in 1.8.0 in scm/define-grobs.scm
there is (font-relative-size . -1)
I sent a sample output from 1.8.0 to a composer (who had only seen
finale, sibelius etc before) he commented
< Thanks for sending it to me. The quality is very impressive, and

One thing he pointed out (amongst other things I am working through) is that the figures in the bass are unconventionally far from the notes they refer to. The figures all begin at the same vertical offset, computed to miss the worst case note. In the hand engraved scores I've looked at the figures start a short distance below the note, or the bottom staff line if the note is entirely within the staff. (i.e. they are ragged top and bottom).
Also the example in the 1.8.0 documentation assumed that the default
direction was going to be #-1, so as it stands it generates a
back-to-front set of figures.
With all this in mind, the following revised example works with 1.8.0
\score {
<
\context Voice \notes { \clef bass dis4 c d ais}
\context FiguredBass
\figures {
\property FiguredBass.BassFigure \override #'font-relative-size = #-3
\property FiguredBass.BassFigure \set #'direction = #-1
\property FiguredBass.BassFigure \set #'extra-offset = #'(0 . 3.5)
\once \property FiguredBass.BassFigure \set #'extra-offset = #'(0 . 2.5)
< 6 >4
< 7 >8 < 6+ [_!] >
\once \property FiguredBass.BassFigure \set #'extra-offset = #'(0 . 2.5)
< 6 >4
<6 5 [3+] >
}
>
}
This is rather verbose - is there some tweak available to make the
figures automatically sit just below whatever is above? I have a
sneaking suspicion that this bit is the right bit to tweak
(BassFigure
...
(Y-offset-callbacks . (,Self_alignment_interface::aligned_on_self))
...
but have no idea how (aligned_on_something_else? :-\ )

Han-Wen Nienhuys wrote: [EMAIL PROTECTED] writes: (a first attempt to post seemed to go into a black hole ... try again ...) The figured bass support in lilypond (wonderful!) is a little tricky to use for three reasons: 1) The figures have to be entered in the reverse order (that is a six-four chord is entered <4 6>). Of course, this assumes that you do call it that and not a four-six chord, but I *think* is universally so. In dutch, <> (absolute pitches) is called a 4-6 chord, not 6-4; that's what you mean, right? yes I'm not sure about the proper names in English. Can you do some more research to find out what is the Right Way? yes - with classic anglo-saxon myopia I referred to the English nomenclature as "universal" ... the research for the Right Way turned out to be very easy - typing "six four chord" into Google yielded 137 hits and "four six chord" yielded 7 hits. For example: "Six-four chord (siks for kord) A chord consisting of three notes, the bass note, the interval of a fourth above the bass note, and a sixth above the bass note. ..." from this site www.music.vt.edu/musicdictionary/texts/Six-fourchord.html and likewise for "four six chord", though less common. However, it occurs to me that I've started us thinking along the wrong lines here - what matters is what people who may want to write figured basses into lilypond will find most natural. I jumped to the conclusion that the reason I write 6 followed by 4 when writing out figured basses was because I call it a six four chord. In fact, since the figures are always aligned at the top there is a much stronger reason why, when writing out the figures you start at the top and work downwards, and hence why you write them out as six followed by four (to continue the example). If you didn't write downwards, you would have to guess where to start writing the figures, judging by how many figures you had to fill in. This all presupposes that figured basses are indeed aligned horizontally at the top: I am sure this is always so, based on sampling Italian, French, English and German 17th & 18th c. sonatas from my bookshelf and thirty odd years of knocking round in early music circles. In fact, I think anything else would appear outlandish, because the commonest figures (a # or b or a six on their own) would have to be placed at some distance from the bass note, depending on the maximum number of figures to be found on any one note in the piece. A # would then frequently appear to be associated with some note on the next line, which usually either means that the editor thinks *that* note should be sharpened (or if ornamented, the ornament should be sharpened). (I feel perhaps I'm labouring the point now ...). I've added #'direction for the BassFigure grob, so you can the stacking direction. (1.7 cvs) The default should be the normal direction else we risk creating another standard in figured bass notation!
