Which of the following is NOT an attribute of the conductor?

The correct answer is that being able to play and conduct at the same time is not an attribute typically associated with the role of a conductor. Conductors are primarily responsible for leading the orchestra, setting the tempo, interpreting the score, and communicating their intentions through gestural language. Their focus is on directing the performance and ensuring cohesion among the musicians rather than performing on an instrument simultaneously.

In contrast, being responsible for interpreting the score, setting the tempo, and communicating through gestures are essential functions of a conductor. They need to understand the musical nuances and translate that interpretation to the musicians, which is done primarily through conducting techniques rather than playing an instrument. Therefore, option B stands out as not aligning with the fundamental responsibilities expected of a conductor.
