Summary:
This is a modern mainstream American teen‑pop instrumental in C major at 120 BPM, 4/4—designed to support a female lead vocal in the late‑2010s/early‑2020s commercial pop style (Olivia Rodrigo / Tate McRae / Ava Max influence). The arrangement centers on a tight pop rhythm section (kick, snare, layered hi‑hats), a layered low end (synth bass + sub/808 + electric bass), midrange harmonic support (digital/electric/acoustic pianos, chord stabs, guitars), and high‑end sparkle (synth leads, arps, strings, brass). Dynamics and section contrast follow the provided energy curve (sparse, intimate verses; building pre‑choruses; big, hooky choruses; a vulnerable bridge; maximal final chorus), with explicit space left for vocal phrasing and breaths. The 29‑stem separation and humanization/CC automation requirements (CC7/11/1/74/10, timing/velocity variation, evolving hi‑hat patterns, fills, and micro‑pitch movement) ensure a professional, playable MIDI that feels organic and radio‑ready while strictly adhering to the specified section counts and instrumentation map.
