This is the bassline played throughout the entire song. 
It sounds very beautiful and relaxing especially on guitar.
If it is too hard for you, you could play "E, A, D6" but it is very simple and can be learned quickly.

RIP. Mac Miller my favorite artist.

************************************

[Verse]
                                                     
Well, this is what it look like right before you fall
                                                         
Stumblin' around, you've been guessing your direction
                                 
Next step, you can't see at all
                                                  
And I don't have a name, I don't have a name, no
                                            
Who am I to blame? Who am I to blame though?
                                                
And I cannot be changed, I cannot be changed, no
                    
Trust me, I've tried
                                            
I just end up right at the start of the line
               
Drawin' circles
   
Mmm
                                               
Well, I drink my whiskey, and you sip your wine
                                                                       
We're doing well, sittin', watchin' the world fallin' down, its decline
                                                 
And I can keep you safe, I can keep you safe, mmm
                                  
Do not be afraid, do not be afraid
                                      
You're feeling sorry, I'm feeling fine
                                                                 
Don't you put any more stress on yourself, it's one day at a time
                                             
It's gettin' pretty late, gettin' pretty late
                
Damn, and I find
                                                         
It goes around like the hands that keep countin' the time
               
Drawin' circles
