Re: Time signature in French baroque music

[Mats Bengtsson]

Regarding the original question, the simple answer, which has already been
given, is to use
\override Staff.TimeSignature #'style = #'single-digit

Regarding Gilles' problems with compound time signatures, I would recommend
to use the example in Sect. "8.4.1 Polymetric notation" as a starting 
point.
Then, you could end up with something like:

\version "2.8.7"

#(define (compound-time-2 one two three four)
 (markup #:override '(baseline-skip . 2) #:number
  (#:line ((#:column (one two)) #:lower 1 "+" (#:column (three four))))))



theMusic = \relative c'' {
 \time 3/4
 \override Staff.TimeSignature #'stencil = #ly:text-interface::print
 \override Staff.TimeSignature #'text = #(compound-time-2  "1" "2" "3" 
"4" )
 a4 b g | f4 g2 |
}

\score {
   \theMusic
   \layout {}
}
