it's not the entire scale, but a sort of collections of notes from the A harmonic minor scale. specifically the 4th, 6th, #7th, 8th, 3rd/10th, and 4th/11th notes in the scale.
scale to 11th degree:
G --------------------------4--5--7-
D --------------------6--7----------
A -----------5--7--8----------------
E --5--7--8-------------------------
please, anyone with more music theory skill than me, feel free to correct my mistakes
