My best guess
The main chords are C and F by the look of it.
The main motif theme sounds something like:
A |------------------------|----------------|
E |-0-1-3--0-1---0--------|-------0---0----|
C |------------2---0-2----|-0-0-2---0---2--|
g |------------------------|----------------|
The second theme sounds like:
A|---------------------|-----------0-1-3-1-0---|
E|----------0-1-3-1-0--|-1-1-1--3-------------|
C|-0-0-0-2-------------|-----------------------|
g|----------------------|-----------------------|
After that it's anyones guess. This sounds ok to me LOL.
I hope this helps a bit - feel free to correct my attempt
Best wishes
Anna
