Antimasque can refer to a specific type of performance that was popular in 16th and 17th century Europe, intended to precede a masque or other form of theatrical entertainment. However, there are other words that can be used to refer to similar types of performances. For example, the term "prelude" can be used to describe an opening performance that sets the tone for a larger event. "Prologue" is also a possibility, particularly if the performance is meant to introduce the plot or themes of a play. Other options might include "introductory act," "curtain raiser," or simply "opening performance." Whatever the specific term used, the intent is to warm up the audience and provide context for the main event.
