Protection song (a poem in progress)

I am still working on this, but wanted to share the first verse.

The violin is what you play 
when you can’t sing.
Red backed fairy wrens 
know their mother’s song
before they hatch 
to protect themselves from
birds of prey. 
The violin is what you play
when your mother didn’t have a song for you,
but you’d like to find your own 
Protection song.
