four intervals? is that how many notes you are determining from my polyphonic lip buzz technique?

No what I meant was your bassline, at least at the front of what you were doing was going down a fourth, like from a C to a lower G type of thing. Kind of in the same way as you would ask, can you see this picture? And I answered and said yes, I can see it's a blue car or something.

Also, it's kind of evident that the 18-second mark.

It's also me just geeking out on the small things, which is almost as bad as the AI.
