The caesura often indicates an abrupt interruption in the performance followed by an equally sudden resumption. Its duration is typically shorter than a grand pause (G.P.) or long pause (L.P.), but longer than that indicated by a <breath> mark. When combined with a <fermata> a longer silence is usually implied. The starting point of the caesura may be indicated by either a @startid, @tstamp, @tstamp.ges, or @tstamp.real attribute. It is a semantic error not to specify a starting point attribute.
Unlike the <breath> mark, a caesura may have a performed duration. Also, while the default value for @place on the breath mark is above, the default value for @place for a caesura is within. Unless indicated by other attributes, a caesura will be rendered as a pair of slanted lines through the top line of the staff.
