I am often asked the question:
"How do you write a song?"
I start with a poem about a personal experience. I jot down the words using a pencil. I like scratching, erasing, crumpling and tossing. I work on the poem until it takes the shape of a few verses, a chorus. and a bridge. After the poem is sketched, I strum chords on my guitar to find a key/sound that matches the emotion or mood of my words. After I find the key, I try different melodies. If it's right, I know it immediately. It is one of the closest things to magic I've experienced.
