Suno prompt
A restless synth-pop track blending orchestral pop with driving energy and a broken-beat feel at 77 BPM. The low end is electric bass playing root-note anchored, under an acoustic drum kit with a clap-layered snare and sparse dark cymbals. Acoustic guitar carries the harmony, fingerpicked. The arrangement follows verse-chorus with a bridge. A full-voiced female vocal delivers a smooth and melismatic performance. Analog hiss adds texture, with a short room reverb on the vocal. Mixed in a bright and modern style, foregrounding harmonic warmth and atmospheric space, built on chromatic and shifting chords, leaving a tense and coiled atmosphere.
Paste this into Suno's style field. It describes the sound only — adjust anything that does not match what you are after.
