🎵 Musical Arrangement 2D: Layered Waves and Roughness

Interactive 2D model of musical arrangement as wave superposition: four instrument layers built from harmonic and bell-like partials on a draggable piano roll, with live waveform lanes, a spectrum and a Plomp-Levelt roughness readout that explains why some chords sound smooth and others beat.
