Other variation in repeated sections

An \alternative block can be used within a \repeat block to produce notation similar to alternative endings (see Alternative endings).

\fixed c'' {
  \repeat volta 2 {
    R1
    \alternative {
      \volta 1 { c1 }
      \volta 2 { d1 }
    }
    R1
  }
}

The \volta command is not limited to use on the elements of an \alternative block. It can be used anywhere within a \repeat to designate music for particular volte, though it does not create brackets in other cases.

When a \repeat is unfolded, volta-specific music is omitted from every volta to which it does not apply. Providing an empty Scheme list in place of volta numbers removes the music entirely.

music = \repeat volta 3 {
  \volta #'() { <>^\markup { \bold "3×" } }
  \volta 1 { <>_\markup { \italic dolce } }
  g''1
}

\score { \music }
\score { \unfoldRepeats \music }

When a \repeat is unfolded, it may be desirable not only to filter out volta-specific music, but also to add music that was not present in the folded form. The \unfolded command designates music to be ignored until the enclosing \repeat is unfolded.

music = \fixed c' {
  \repeat volta 2 {
    c1
    <<
      \volta #'() {
        \once \override TextSpanner.bound-details.left.text =
          "2nd time tacet"
        s4*7\startTextSpan s4\stopTextSpan
      }
      \volta 1 { f4 f f f | f f f f }
      \volta 2 { \unfolded { R1*2 } }
    >>
    c'1
  }
  \fine
}
