I don't think it does have a resonant frequency, any more than the Earth
does: the angular velocity of the pendulum is sqrt(g/h) where h is the
height of the pendulum; give it more energy, it swings higher, so h is
smaller, so the frequency is higher.

South Thames, Dover: Southwesterly 5 or 6. Slight or moderate. Rain or
showers. Good, occasionally poor.
