Stichomythia

Stichomythia (Greek: Στιχομυθία) is a technique in verse drama in which sequences of single alternating lines, or half-lines (hemistichomythia) or two-line speeches (distichomythia) are given to alternating characters. It typically features repetition and antithesis. The term originated in the theatre of Ancient Greece, though many dramatists since have used the technique. Etymologically it derives from the Greek stikhos ("row, line of verse") + muthos ("speech, talk").
