Again by Alice in Chains

I dont know the song that well but here are the parts.
Work with the arrangement.  I'm assuming the chorus
is the part where Layne goes "ooh ooh".  Also in the
chorus, the harmonics are played in a quick slide, 
resemblent of the Smashing Pumkins song 'Zero'. These 
same figures are repeated throughout the song.
