The repeated music is not written out but enclosed between repeat bar
lines. If the repeat is at the beginning of a piece, a repeat bar
line is only printed at the end. Alternative endings (volte) are
-printed, left to right with brackets. This is the standard notation

@c Is there a way to have a final bar ("|.") at the end of the
@c previous line? Doesn't seem to be.
+@c It could be done by overriding
+@c the BreakAlignment property. Want a separate example?
If you want to start a repeat at the beginning of a line and have a
double bar at the end of the previous line, use @code{\bar}. For more
information, see @ref{Bar lines}.
Timing information is not remembered at the start of an alternative,
so after a repeat timing information must be reset by hand; for
example, by setting @code{Score.measurePosition} or entering
-@code{\partial}. Similarly, slurs or ties are also not repeated.
