A writer doesn't possess timbre in the auditory sense.

Writing is not so much about how the words sound—
at least not to me––
as it is about how they look, feel and read in one's head.

This makes sense when you consider that while songwriting is heard, writing is seen.

A writer on the page will never be able to compete with a singer-songwriter.
While I'm a bibliophile, I constantly find myself reaching for music over literature.
I can't get enough of the stuff.

I think there is something primal about music 

that has snaked its way deep into our DNA.
By 12 months, all of us instinctually begin singing short phrases,
long before we're capable of reading and writing.

So, what is a writer's job in all of this?

I don't fucking know...
