The library is built around a custom-tuned Kukke handpan, known for its warm attack, long sustain, and clean fundamental tones. Unlike mass-produced steel tongue drums, a true handpan has a resonant, "soft bell-like" character with a distinct scape (the central note) and a circle of tuned dimples around it. Ergo Kukke captures this specific instrument’s tuning—typically a mystical, fifth-based scale (often around D minor or Celtic-inspired modes)—giving the library a melancholic yet hopeful emotional core.
