Prompt Log
The prompt is preserved verbatim as part of the documented artifact.
Create a historical music track representing the birth of polyphony, where multiple melodic lines begin to move together. Use layered human humming with invented syllables only, early strings, simple flutes, and very soft percussion. No real language, no modern instruments, no electronic production, no religious references. The composition should begin with one simple melody, then gradually add second and third melodic lines that interweave naturally. Make it feel like music discovering depth, harmony, and vertical structure for the first time.
