Conducting is the art of leading a musical ensemble, such as an orchestra or choir. The conductor uses hand gestures, facial expressions, and a baton to communicate tempo, dynamics, and emotion to the musicians. This guidance helps ensure that all performers play in harmony and synchronize their parts effectively. The role of a conductor is crucial in shaping the overall sound of a performance. They interpret the score, which is the written music, and convey their vision to the musicians. Famous conductors, like Leonard Bernstein and Herbert von Karajan, have made significant contributions to classical music through their unique styles and interpretations.
