Rehearsals are practice sessions where performers prepare for a show, such as a play, concert, or dance performance. During rehearsals, actors, musicians, and dancers work on their lines, music, or choreography to ensure they are ready for the final performance. This process helps them become familiar with their roles and the overall production. Rehearsals can vary in structure and length, often including full run-throughs or focused practice on specific scenes or songs. They are essential for building teamwork and improving the quality of the performance, allowing the cast and crew to address any issues before the actual event.
