I’m not done with it yet, but I do need to keep in mind that I don’t have to use it all the time. I suppose I’ll fall in love with another strange-ish modulation in time, and then another, etc. And at some point, I’ll be able to use varied ones. But for now, I love IV-iv-I. And I seem to be enjoying mixolydian. There’s something nice and leisurely about a major scale without a raised seventh. You get all the yumminess of the nice fifth, fourth, and third, and all the laid-back quality of the whole step up into the tonic. It’s like the modal equivalent of sipping sangria while sitting in an Adirondack chair on a Sunday morning.
