Musical repeats.
There are three modes of representing this music:
BODY A
- B
- C
+ B
+ C
is called "folded". Mostly used for lyrics.
-

BODY A B C
is called volta. This is common notation
If the number of repeats is bigger than the number of alternatives, then
the first alternative is assumed to be repeated.
