Half-step Down Tuning:
Many of Horror by Biffy Clyro
Verse
Playing what the lead is Playing here, I suppose it's a bit of a combo of lead and 
chords! You'll have to do your own timings!
Sorry for the mess; this is my first real tab!

Key:
/ Slide up the neck
\ Slide Down the Neck
( )Note continued 
{ } Everything inside is included
x muted string

NOTE: if after / or \ a note is not contained within brackets then play it again!
Also when you get to the part with the Open 0 on the D string, it's optional 
whether to play that or not, I choose not to but I included it anyway, I just mute it!
