It's one note from 1:39 to 2:53. Same note from 4:00 to the end. Most of the other time there only one note being played within a bar or two or four with a repeated rhythmic figure. Dotted 8th 16th note, 8th 8th, 8th rest 8th, 16th 16th 8th.
I'm looking forward to seeing color on the trees here like on that album cover.
