Markers can be placed and referenced at any point during a score, and in any
instrument part. e.g. %chorus
will place a marker called "chorus" at the
current offset, and then using @chorus
at any point will set the current
offset to that of the "chorus" marker.
A marker cannot be referenced before it is placed -- for example, the following score will result in an error:
piano:
@someMarkerThatDoesntExistYet
c8 d e f g2
guitar:
r1
%someMarkerThatDoesntExistYet
Instead, the placement of the marker must occur before the marker is referenced:
guitar:
r1
%existingMarker
piano:
@existingMarker
c8 d e f g2
Marker names follow the same rules as instrument names.
