Is there an easy way in arranger.ly to quote a theme or motive with one
command in different or voices?
What would be e.g. if You have a fugue with the dux in soprano, alto,
etc.
in different voices at different places in the score?
Well, in one command, not directly because a lot of parameters are
involving. You have to make your own function.
%%%%%%%
\version "2.22.0"
\include "arranger.ly"
global = { s1*8 }
#(define all '(bas ten alt sop))
#(init all)
theme = { c2 d e c }
#(define (dispatch-theme instru step where)
(rm instru where ((set-transp 0 step 0) theme)))
#(for-each
dispatch-theme
all
(list 0 4 7 (+ 4 7)) ; 4 = a 5th, 7 = an octave
'(1 3 5 7)) % bar 1 3 5 7
\new ChoirStaff <<
\new Staff {
<< \global \sop >> }
\new Staff {
<< \global \alt >> }
\new Staff {
<< \clef "G_8" \global \ten >> }
\new Staff {
<< \clef bass \global \bas >> }
%%%%%%%
Note than an automation in a fugue can be difficult, because sometimes
the theme when transposed in the 5th, is slightly different. (in french
we call that a "mutation", don't know the English for that)
