|------3-------3h5----------3---------------10------10h12------|
|--3h5---5-5-----------3h5-----5-5-----5/12-----/12------------|
|-------------------3------------------------------------------|
This is more or less repeated with little change throughout the whole song -
Although, a few times in the song - - he'll do:
|----------------------------------------------------------------|
|---------------3h5------------3----------------10-------10h12---|
|-5-5-5-5-5---------------3h5-----5-5-----5/12------/12----------|
|--------------------3-------------------------------------------|
Just listen to the song for timing...
