Begin with a unifying theme that recurs throughout the piece, representing the collective spirit of the community. A strong, rhythmic motif in a major key symbolizes foundational resolve.
Introduce variations of the main theme for each contributing group, reflecting their unique characteristics. Use ornate and intricate motifs for goldsmiths, robust ones for builders, etc., to capture diverse contributions.
Use interludes of ascending sequences between variations, representing the ongoing construction and progress, increasing in intensity and complexity as the walls rise.
Introduce a section in a minor key to depict challenges faced during construction, using dissonant chords and a slower pace to reflect fatigue and struggle.
Bring back the main unity theme in a grand reunion of all variations towards the climax, merging all individual efforts into a powerful, harmonious whole. Increase dynamics for impact.
End with a celebratory section, reintroducing the unity theme with embellishments and a triumphant modulation, celebrating the successful collaboration and renewed strength of Jerusalem.
