An orchestral conductor is a musician who leads an orchestra during performances. They use hand gestures and a baton to communicate with the musicians, ensuring that everyone plays together in harmony. The conductor interprets the music, deciding on the tempo and dynamics, which helps shape the overall sound of the performance. Conductors often study music theory and composition, and many have experience playing instruments. They work closely with the orchestra to prepare for concerts, rehearsing pieces and providing guidance. Their role is crucial in bringing the music to life and creating a cohesive performance for the audience.
