A rehearsal is what takes place before the actual event.
An example of a rehearsal is when you need to practice a play before it is shown before an audience. In this case you can also have a 'dress' rehearsal which is when the rehearsal is done with the characters in the play wearing the actual clothes they would when they perform in front of an audience
