Duelling banjos from deliverance for guitar
Tabbed by me
Tuning: E,a,d,g,b,e

Guitar only as I have no banjo


INTRO: this is the famous bit that freaks people out.
  
e|-----------------------------------------------------------
b|-----------------------------------------------------------
g|-------0---------------------------------------------------  this bit is 
d|-2-2/3---2-3-0-2---0---------------------------------------  100% right
a|-----------------3-----------------------------------------
E|------------------------3----------------------------------

Verse this is basically a C chord but certain strings plucked and finger positions move. This is a simplified version which sounds good when played fast
e|--------------------------------------------------------------
b|-1------1-----1-----1-----0-----0-----------------------------
g|----------------0h2---0h2------------------------------------- repeat 
d|---0h2----0h2-3-----3-----------------------------------------
a|-3------3-------------------0h2---0h2-------------------------
E|--------------------------3-----3-----------------------------

The rest is very similar just variations and change in time 
but to sound same as in film you need a banjo?to play along to.

I don?t know order or anything coz I only seen film once? never again lol.
