MuseScore -- Index -- Volta

Volta brackets are used to mark different endings in a repeat:



The brackets can span more than one measure. Double click the volta to enter edit mode and then move the handles with:

<Shift+Right>   one measure left
<Shift+Left>   one measure right

This commands move the "logical" start or end of the volta which determine the bracketet measures. Other commands in edit mode also move the handles but do not change how the repeat is played. If you move the handles, a dashed line from the logical position to the actual position is shown



Properties
Repeat List
This list determines in which repeat the volta should be played. If the volta is played in more than one repeat all repeat numbers must be entered separated with a ",".

Text
You can set an arbitrary volta text. Of course the text should correspond with the repeat list.
