"caption": "an orchestral home voice with a single solo carrier. a single solo french horn as the carrier, warm and unforced, over a quiet string frame. A 4-note triad-outlining head motif with exactly one memorable interval event: an unusual leap. a four-note head that is recognisable within its first few notes; regular harmonic rhythm, one chord per bar, so the grid never moves while the harmony under it does; sentence form: basic idea, basic idea, continuation, cadence, in 2+2+4 bars; the continuation by fragmentation of the opening cell, not by new material; the loop ends open rather than landing finally. Mood: heroic, contemplative, hopeful, warm. Fully instrumental, no voices, no singing, no lyrics. No drum kit, no synthesizer, no electric guitar, no modern pop production. Clean start and clean end with no fade in and no fade out. Continue and vary the material already present; keep the same motif.",
