The 16 F-operators of the EML family laid out as an orchestra. Each cell plays the cost-class sound of its canonical expression (same Pfaffian → audio mapping as the Sound of Math page). The four corner cells F13-F16 are the composite operators that drive the EML self-map fractal at /visual/fractal-explorer.
The gold cell at the bottom is the guest oscillator:p2-d5-w2-c1 — the universal canonical-oscillator class. None of F1-F16 land in it directly (they are seeds, not fully-formed oscillators); the guest demonstrates what that class sounds like.
