Do We Lose 21 Grams

you have to figure out the timing but it generally goes like this..

standard tuning
|---------------------------------------------------------------- 
|---------------------------------------------------------------- 
|-----------------------------------------------4-2~------------- 
|4h5h4~---4h5h4~--4h5h4~----4-5~--4h5h4~---4h5h4------4h5h4~----0 
|---------------------------------------------------------------0 
|------5~---------------5~--------------5~------------------5~--5 

also in the background something like this fades in
|--2--|--2--|--2-0-| one of those repeated, its too quiet to tell. 
|---0-|---0-|------|                                               
|-2---|-4---|-2----|                                               
|-----|-----|------|                                               
|-----|-----|------|
