The prompt
A tender folk track blending indie rock with explosive energy and a broken-beat feel at 123 BPM. The low end is electric bass playing root-note anchored, under an acoustic drum kit with a clap-layered snare and washy crash-led cymbals. Clean electric guitar carries the harmony, fingerpicked. The arrangement follows AABA. A full-voiced female vocal delivers a smooth and melismatic performance. Subtle bitcrush adds texture, with a slapback delay on the vocal. Mixed in a clean and spacious style, foregrounding vocal clarity and low-end weight, built on chromatic and shifting chords, leaving a calm and settled atmosphere.
