Great! It works! It works!
Thank You!

to make a function with argument list or vector

[Оксана Крымина]

hello all!

please, help me to write a function to convert several numbers like (5
7 10 8) to musical string like
 \repeat unfold 5 {c2} \bar ""
 \repeat unfold 7 {c2} \bar ""
 \repeat unfold 10 {c2} \bar ""
 \repeat unfold 8 {c2} \bar ""

my code produces errors only:
\version "2.18.2"
musSpisok = #(define-scheme-function (parser location llen)(list?)
(if (not (null? llen))
#{
  \repeat unfold $(car llen) {c2} \bar ""  (
\musSpisok #'(cdr llen))  )
#})

thanx,
Oxana

Re: Variables: multiple use with multiple stanza

[Оксана Крымина]

Michael,
Thank You a lot! I will use this way.

I would just write a plain simple melody and whereever you need

Variables: multiple use with multiple stanza

[Оксана Крымина]

Hello all!
I engrave ancient russian church music in original notation (by \lyricmode)
and common score. This is single-voice music: one score + one string of
ancient notation ( + one string of words). But SOMETIMES there is TWO
strings of ancient notation under 1-2-3 notes. There I use construction
with \new Voise inside my music and \lyricsto this voice (new and context).
In case of multiple use of some music I use variables. The problem is: if
variable containes  \new voice = ... { ... } I can use this voice only
once. Secon use has no lyrics to this voice.
What's wrong?

Sample:

kulism = \relative c'  { e4( f) g( f) e( f e d)  \new Voice = "cdcb" { c( d
c b) } a1 }
slov = \lyricmode {  mifa solfa mifamire  l  }
\score
  {
  <<
\new Staff   <<   \new Voice = "one" { \relative c'  \kulism
\kulism \kulism }>>
\new Lyrics = "drob" \lyricsto "cdcb"{  "malozakr" }

\new Lyrics = "kr"  \lyricsto "one"   { \slov  \slov  \slov  }
\context Lyrics = "kr"  \lyricsto "cdcb" { doredosi }

  >>
  }

Regards,
Oxana
