Why might a conductor choose an oratorio over an opera for a concert performance?

A conductor might choose to perform an oratorio over an opera for a concert setting primarily because oratorios do not require elaborate staging. This is significant because oratorios typically rely on the power of the vocal and instrumental music to convey their message, rather than the theatrical elements such as sets, costumes, and acting that are essential in operas.

The simplicity of presentation makes oratorios more adaptable for concert performances, where the focus can remain primarily on the music and the narrative conveyed through it. This allows for a more straightforward setup, which can be especially beneficial in venues where resources for staging and production are limited or where the emphasis is on the musical experience rather than dramatic performance.

In addition, oratorios are often performed in concert format, allowing the audience to engage with the music in a different way than they might during an opera, where visual elements play a crucial role in storytelling. Thus, the choice of an oratorio can enhance the experience of the music itself without the distractions or complexities that accompany theatrical productions.
