Arrangement-aware melody writing is a highlight. A melody that works solo may vanish in a dense mix; conversely, an overly busy production can cover delicate phrasing. The guide lays out simple arrangement rules: register slots for lead, doubling, and countermelody; how to carve space with instrumentation; and when to thin textures for lyric clarity. Free stems for three arrangement templates (sparse acoustic, mid-density pop, full cinematic) let you audition how a melody behaves across contexts.
