What does unison mean in drama?

Unison in drama refers to two or more characters speaking at the same time, usually delivering the same line or lines in perfect synchronization. This technique creates a sense of unity and solidarity among the characters, emphasizing a common goal or purpose. It can also amplify the impact of a particular line or sentiment by intensifying its emotional resonance through multiple voices. Unison is often employed for moments of heightened drama, such as rallying cries, vows, affirmations, or declarations.
