Hey, hey

I was listening to The Last Baron by Mastodon. Around 6 mins into the song is this whacked out little interlude with this awesome sounding descent of notes . I think the notes go as follows:


It looks like it's just a basic pattern working its way down the strings. I really like the way it sounds, but I frankly have no idea what it's based off. I think it's a really cool sound to have in my arsenal.
Anyone know what's potting here? Thanks all
mastodon doesn't tend to think much when they write, which is why is seems so out there. it's just what feels/sounds good, and it's just what you said - a little ditty copied a few steps down a couple times.
