Mode one hums a gentle tune,
Soft vibrations, calm and mild.
Mode two flirts beneath the moon,
Mode three? The beast runs wild!

Transmissibility starts to climb,
Phase spins round without a care.
Raise the frequency, feel the rhyme—
The structure dances through the air!

A gentle breeze across the beam,
Mode one hums a quiet song.
Mode two stirs a daring dream,
Mode three shakes the world headlong!

Foam is pressed, the shaker hums,
Vibration sings through silent strain.
Dynamic plots, the insight comes—
A spectral tale in damping’s reign.

The signal hums in time’s own thread,
A dance of force through foam and air.
FFT reveals what modes have spread,
The spectral truth begins to flare.
