Cool Case Café

Create cafe-style instrumental background music for focused study, specifically for solving multiple-choice law exam questions (judicial exam, law school entrance, bar exam, judicial scrivener). It should support sustained attention and mild cognitive activation for output tasks. Style: minimal jazz / cool jazz. Tempo: 90–110 BPM. Mood: calm, neutral, stable with slight forward motion and light groove. Rhythm: mostly straight or very light swing, minimal syncopation. Harmony: simple (up to 9th), minimal modulation. Instrumentation (clean, clear sound): piano (main, comping), upright bass (simple walking/root), soft brush drums (very minimal, no harsh cymbals/snare), soft electric piano (light pad). Melody: short, subtle repeating phrases, no long solos. Structure: loopable, minimal variation, stable dynamics (±10–15%). Mid-range focused, avoid excessive highs. No vocals, no aggressive drums or strong brass. Non-intrusive, clear sound. Length: as long as possible (~8 min), seamless loop
