I was tone deaf half my life, until I fell out of the crow’s nest and woke up with perfect pitch. There are no other cases in the annals or in their executive summaries.

Down at the switching yard, the locomotives were idyling in C, but not a well-tempered sea. The vibrations are arbitrary, but the harmonics are pythagorean. Abstain from beans.
