Some \override commands require a pair of numbers
(called a cons cell in Scheme). To pass these numbers
into a function, either use a pair? variable, or
insert the cons into the music function.
manualBeam =
#(define-music-function (parser location beg-end)
(pair?)
#{
\once \override Beam #'positions = #$beg-end
#})
\relative {
\manualBeam #'(3 . 6) c8 d e f
}
or
manualBeam =
#(define-music-function (parser location beg end)
(number? number?)
#{
\once \override Beam #'positions = #(cons $beg $end)
#})
\relative {
\manualBeam #3 #6 c8 d e f
}
