I made this after moving my piano to a window and watching the world outside. It's quite windy today, so the tops of the trees were moving about, and birds were gliding through the air. I guess those were the inspirations for this song.
The chord progression is pretty repetitive, but no matter how hard I tried, I seemed to just keep adding to the song without changing it.
I also kind of messed up at the end, but the last part was practically improv, and I had trouble replicating the rest of it, so I just kept it as is.
