Which musical component does not typically appear in oratorios?

In the context of oratorios, the musical component that typically does not appear is sets and costumes. Oratorios are large-scale musical compositions for orchestra, choir, and soloists, often with a religious or narrative theme. Unlike operas, which involve theatrical performances with sets, costumes, and acting, oratorios are more focused on the music itself and are usually performed in concert settings without elaborate staging.

Choruses, solos, and instrumentation are all integral parts of oratorios. Choruses provide a powerful vocal ensemble experience, often contributing to the narrative and emotional depth of the piece. Solos allow individual performers to showcase their vocal abilities and express the character's emotions. Instrumentation supports the vocal parts and adds texture and color to the music, making it a rich auditory experience. In summary, the absence of theatrical elements like sets and costumes in oratorios distinguishes them from operas and aligns with their primary emphasis on musical expression.
