Trunk Rattle

[Intro: isolated sine sub-bass, slow fade in, 34Hz pure tone] [Verse: bass floats along sinusoidal path, smooth pitch modulation, cabin pressure build] [Pre-Drop: low-end swell, sub-harmonic saturation, anticipation] [Drop: maximum sub-bass impact, 34-36Hz sine wave, trunk rattle, sinusoidal glide, deep vibration] [Bridge: stripped to fundamental frequency, slow sine oscillation, infrasonic rumble] [Final Drop: layered sub-bass, resonant low-end, car test mode, system overload] [Outro: gradual sine decay, bass fades to silence, residual vibration]
