What is a key responsibility of a music director (conductor)?

A key responsibility of a music director, also known as a conductor, is to choose the music for live performances. This role involves selecting compositions that will be performed by the ensemble, ensuring that the pieces align with the theme of the concert or the artistic vision of the performance. The music director’s selection can greatly impact the overall experience of the audience and the effectiveness of the ensemble's performance.

In addition to choosing the repertoire, the music director also shapes interpretations of the chosen pieces, makes decisions regarding arrangements, and guides the musicians during rehearsals and performances to achieve a cohesive sound. This responsibility highlights the conductor's critical role in both the artistic and logistical aspects of live music performances.

While other roles mentioned may be relevant in a broader musical context, such as recording or training musicians, they are not primary responsibilities of a music director. The essence of a conductor's work revolves around repertoire selection and the leadership of musicians during performances.
