Does the earth resonate on the 'c' pitch ?

Answer 1

Resonance is when the driving frequency (in this case the frequency of the c note) matches that of the natural frequency of an object (in this case the earth) causing an increase in wave amplitude. The earth is made up of so many substances, each with a different resonance frequency that it is not possible for it to resonate as a whole.

In earthquakes the ground can resonate if you take this a the earth in this context, but seismic wave frequencies differ to that of sound frequencies so again there is no resonance.

Answer 2

The earth can sustain multiple resonant frequencies. None of them are audible: all are classed as 'infra-sonic' - too low to hear.

When a big earthquake occurs, the earth rings ...

[quote from the source below]

The "notes" of the bell, or normal vibrational modes, are at extremely low frequencies: the two strongest modes have periods of about 35.5 and 54 minutes. These oscillations died out within a few weeks. Another mode, the so-called breathing mode, consists of the whole Earth rising and falling at once with a period of 20.5 minutes. This pulse was detectable for several months afterward.

A simple search may reveal the correct answer if there is a correct answer that is!

If it did, then Bachs 4'th Brandenberg Concerto would cause it to go into sympathetic resonance until it shook itself to pieces.
