New to Song Lyrics - Seeking Tips!!

Hi Steemit!

So my partner and I are going to start making some music; she being the melodious genius on the keys, and me...well maybe I'll put some words to it. But I've never written songs before, so I'm at a bit of a loss as to what to do. I mean, I'm happy to pull a Bjork and try to eloquently mash words into rhythm, but I figured someone out there must be good at this and can help me out! So any tips on process or song cadence would be so helpful.

Thanks all!
