What element is not usually found in the structure of a choral piece?

In a typical choral piece, the primary focus is the vocal arrangement and collaboration of the singers, which is structured around the components that facilitate choral performance. An introduction sets the stage for the piece, often providing context or establishing the mood. The chorus itself is the central part of the composition, where the choir sings the main thematic material, contributing to the overall cohesiveness and identity of the work. Additionally, a bridge can serve as a transitional section that connects different parts of the piece, enhancing the flow and dynamics of the performance.

Instrumental solos, while they may occasionally appear in some compositions, are not standard components of choral structure. In fact, choral works primarily emphasize vocal harmonies and the collective sound produced by singers. Therefore, the presence of an instrumental solo, which places emphasis on a single instrument rather than the cohesive vocal ensemble, is not typical within traditional choral arrangements. This makes it the element least likely to be found in the structure of a choral piece.
