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

-Alternative endings are entered with

@subsubsection Tremolo repeats
+Tremolos can take two forms: alternation between two chords or two
+notes, and rapid repetition of a single
+note or chord. Tremolos consisting of an alternation are indicated by
+adding beams between the notes or chords being alternated, while
+tremolos consisting of the rapid repetition of a single note are
+indicated by adding beams or slashes to a single note.
