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
-for repeats with alternatives.

@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}.
