Suno prompt
A wistful jazz track with high energy and a swung feel at 59 BPM. The low end is upright bass playing root-note anchored, under an acoustic drum kit with a rimshot-forward snare and a ride-driven pattern. Grand piano carries the harmony, block chords. The arrangement follows loop-based with dynamic drops. A saxophone leads, improvising over the changes. Tape saturation adds texture, with a slapback delay on the lead. Mixed in a lo-fi and saturated style, foregrounding melodic lead and low-end weight, built on extended seventh 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.
