What compositional principle is reflected in the alternation of orchestra and soloists in "Thou Shalt Break Them"?

The alternation of orchestra and soloists in "Thou Shalt Break Them" exemplifies the ritornello principle. This principle is rooted in the Baroque concerto genre, where a recurring theme (the ritornello) is played by the full orchestra, interspersed with contrasting segments featuring soloists. This structure creates a dynamic dialogue between the orchestra and the soloists, allowing for thematic transformation and varying emotional expression throughout the piece.

In "Thou Shalt Break Them," the interaction between the orchestral forces and the soloists can be seen as a showcase of this interplay, highlighting different musical ideas while maintaining a cohesive structure through the returning ritornello material. This approach emphasizes the roles of both the collective orchestral sound and the individual voice of the soloists, leading to a rich listening experience that captures attention and showcases virtuosity.
