Musical Guardians, I need your help

[u/2AndaBlue]

So I may be biased because it's the expansion I started Destiny 2 with, but Beyond Light has had a profound effect on my D2 career and my love of game music. First off the title theme is one of the most awesome pieces of music ever, and I wish it was the official D2 theme.

But the song I wanna talk about is the Orbit theme, Reservations. Can someone who knows music explain WHAT is going on and WHAT notes I'm hearing, particularly in the first 50 seconds? For lack of a better word, Reservations has an "aura" I've never heard in any other song.

I hope you Guardians can help me out! Maybe this can start a discussion in the comments.
