Conducting is the art of leading a musical ensemble, such as an orchestra or choir, to ensure that all musicians perform together harmoniously. The conductor uses hand gestures, facial expressions, and a baton to communicate tempo, dynamics, and phrasing to the musicians. This role is crucial for interpreting the music and maintaining the overall cohesion of the performance. A conductor often studies the score of a piece, which is the written music for all instruments involved. They must understand the nuances of each part, including the roles of different instruments like violins, trumpets, and percussion, to effectively guide the ensemble during rehearsals and performances.
