Raining Blood Tab de uke por Slayer

This is my favourite song. on uke is played in normal tuning( G C E A ).  this is the main  riff:

 -----------9-10-9-----|----9-8----8-7----|
 --------8-------------|-10-----9---------|
 --0-0-0---------------|------------------|
 ----------------------|------------------|
 and then:
 -----------11-12-11---|----10-9---9-8----|
 --0-0-0-10------------|-11------10-------|
 ----------------------|------------------|
 ----------------------|------------------|

this is the intro of the song.
