I've been relying very heavily on my instincts as of late, and my songwriting has come to depend on my ability to surrender to the inspiration whenever it strikes. When I clear my mind and let the music take over, my hands seem to move on their own, and my voice utters words I haven't premeditated. This is pure instinct. It's like riding a wave. You just take a deep breath, hop on, and hang on as long as you can. That's basically how I songwrite when I'm composing impromptu pieces. It's a lot like channeling. Or free associating. And it's super fun, because anything can happen! It's pure creativity.
