Help transcribing a source

[Modus]

I'm trying to transcribe this Skies of Arcadia piece. There's 3 patterns at the beginning, and I've figured out two but I really can't figure out the third. I have some tone deafness, I guess, because I gave it an honest try

It starts out like Bum-bum-bum-bum-bum-bum [pause] bum-bum-bum-bum-bum-bum-bum [pause] And this next part is what I can't figure out.

So if anyone could write out the beginning patterns in note form I would give my eternal gratitude. This is the source:

Thanks for any help.

(Hope I'm understanding you right)

G Ab F G Ab Eb

D G Ab Eb G Ab D

Ab Eb G Ab F G Ab G

G Ab F G Ab Eb D C Bb Ab

(The second repetition is slightly different jsyk)

G Ab F G Ab Eb

D G Ab C G Ab F

Ab Eb G Ab D G Ab F

G Ab G D Eb Bb G D

(And then it goes down roughly like this)

G D F Bb D G Bb F G D F Bb D G Bb F

(Hope I'm right haha)

Thanks so much evory! I think I changed 1 or 2 notes in your patterns, but even if it's slightly wrong it sounds amazing
