The 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.

This is an independent acoustic analysis. Tempo and key are measured from the audio; instrumentation and production characteristics are classified against a fixed vocabulary. The source recording is deleted once the analysis finishes, and no lyrics from it are stored. The measurements and classifications are automated estimates, so use them as a starting point and trust your ears.
