A baton is a slender stick used by a conductor to lead an orchestra or musical ensemble. It helps the conductor communicate tempo, dynamics, and expression to the musicians. The baton allows for clear visual cues, ensuring that all performers stay in sync during a performance. Typically made of wood, fiberglass, or plastic, batons vary in length and weight to suit the conductor's preference. The use of a baton dates back to the 18th century, evolving from the practice of conducting with a sword or stick. Today, it is an essential tool in classical music and other genres.
