is a poetic meter
that is characteristically used in Greek tragedy
, expressing extreme agitation or distress. There are examples in satyric drama and Aristophanes
, but these are often paratragic in tone and impassioned. The base metrical scheme is: u — — u —, although any of the long syllables may be resolved and either of the two shorts may be replaced by a long (drag-in
where the first is replaced, drag-out
where the second is replaced, and double drag
where both are replaced).
