I tried to do it. I failed. My song is 102 words long. By Iggy's and Soupy's standards, quite verbose. I was playing a borrowed Martin guitar, a smaller-bodied one, mahogany, super-nice and easy to play. It sounds so good ringing out in the kitchen, high ceiling, hard surfaces, lots of nice reverb. I tend to use an alternate turning, it makes standard chords sound a bit foreign. I just tuned up and started banging away. I am always surprised when the words and chords start to work together to create unique lines of melody. I worked on the song for hours and recorded a demo on my little smart-flip-phone. Like I said, not earthshaking. But it was pretty consuming and exciting for me. That's the beauty of the creative thing, it's a flow activity. You push yourself into the flow and ride. Nothing better.
