When I hear this song I think of kites and bubbles : ) I like the moods it goes through in the space of five mins. The tempo changes, it’s loud then soft, it ebbs, it flows, it soars in places and swirls up, up, up. I feel like I’m flying in the sky listening to this. It’s in E minor today with a simple chord progression which sounds like bubbles making their way to the surface to pop.
