#### Alternative endings

Repeats with alternative endings can be written two ways. This is the preferred syntax:

\repeat volta repeatcount {
musicexpr…
\alternative {
\volta numberlist musicexpr
\volta numberlist musicexpr
…
}
}

where musicexpr is a music expression, musicexpr… is any number of them, and numberlist is a comma-separated list of volta numbers chosen from the range 1 to repeatcount.

\fixed c'' {
\repeat volta 6 {
c4 d e f
\alternative {
\volta 1,2,3 { c2 e }
\volta 4,5 { f2 d }
\volta 6 { e2 f }
}
}
c1
}

An older syntax where the \alternative block follows outside the repeated music expression is still supported and has the same effect.

\repeat volta repeatcount musicexpr
\alternative {
\volta numberlist musicexpr
\volta numberlist musicexpr
…
}

\volta specifications within an \alternative block are optional on an all-or-none basis. If they are omitted, alternatives are used once each, but the first is repeated as needed to satisfy the repeat count.

\fixed c'' {
\repeat volta 6 {
c4 d e f
\alternative {
{ c2 e }
{ f2 d }
{ e2 f }
}
}
c1
}

\alternative blocks can be nested.

music = \fixed c' {
\repeat volta 3 {
s1_"A"
\alternative {
\volta 1 { s1_"B" }
\volta 2,3 {
\once \override Score.VoltaBracket.musical-length =
\musicLength 1
s1_"C"
s1_"D"
\alternative {
\volta 2 { s1_"E" }
\volta 3 { s1_"F" }
}
}
}
}
\fine
}

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

Note: Every element in an \alternative block is treated as an alternative ending. Something as simple as a bar check on the wrong side of a bracket can produce unexpected results.

Note: If you include \relative inside a \repeat without explicitly instantiating the Voice context, extra (unwanted) staves will appear. See An extra staff appears.

Note: When alternative bar numbering is enabled, it is applied to the outermost bracketed alternatives.
