Riffs are x4

Chorus
This can be tricky because the notes played are far appart, this is what I do:
D3 and A8 are the same note: F
G---------------------------------------------------------------|
D-------------------------------3-------------------------------|
A-8-5-3-5---3-5-----Silence-------5-3-5---3-5-----Silence-------|
D---------5---------Silence-------------5---------Silence-------|

That riff is played 4 times during the chorus

The ending is the chorus riff without the silence so:
G-----------------------------|
D-3-------------3-------------|
A---5-3-5---3-5---5-3-5---3-5-|
D---------5-------------5-----|
