The Earth's orbital period is 365.256 days or 31,558,150 seconds and so has a frequency of 3.169 x 10⁻⁸ Hz which is a Db 33 octaves below middle C that is flat by 31 cents.
The Earth's rotational period is 23h 56m 4s or 86,164 seconds and so has a frequency of 1.161 x 10⁻⁵ Hz which is G 24 octaves below middle C that is flat by 11 cents.
So here we are, floating in space on a slightly flat and slightly out of tune tritone.
