At the heart of each of us,
whatever our imperfections,
there exists a silent pulse of perfect rhythm,
a complex form of wave forms and resonances,
which is absolutely individual and unique,
and yet which connects us
to everything in the universe.
For some birds, songs are learned by listening to their parents and neighbors during the first year. For other birds, songs are hardwired -- the music is scored in their brains from the beginning. For mockingbirds, singing is a lifetime of choir practice and talent shows, picking up new tunes and modifying old ones.
