This is the riff that opens up the song and appears near the end of the
song:

E|------------------------------------
B|-----4-------4------4------1---3----
G|-2-3-----2-3----2-3----2-3--------3-
D|------------------------------------
A|------------------------------------
E|------------------------------------


After this riff is played three times, the keyboard riff that appears is:

E|-------3--------3----------------------3--------3--6--6-6-6--4--3--
B|-4--6-----4--6-----4--1--1--1--4-4--6-----4--6---------------------
G|-------------------------------------------------------------------
D|-------------------------------------------------------------------
A|-------------------------------------------------------------------
E|-------------------------------------------------------------------


This is played two times, then the drums come in and then a weird effect
appears, I think it is harmonics played like:

E|-----------------------------------------
B|--7-7--7--7-7--7-7---5--5-5--5--5--5-5-5- <--play the 5 repeatedly for
G|-----------------------------------------    six times then play, on 
D|-----------------------------------------    the high E string a fifth
A|-----------------------------------------    fret harmonic repeatedly.
E|-----------------------------------------


This appear throughout the song, also with a staccato C note played on
the fifth fret of the G string, during the song.

The main part of the song, is mainly the bass riff which repeats itself
over and over again for eight minutes of the song.  If you don~t know
alread s indicates a slide, p indicates a pull-off and ~ indicates
tremolo.  Here is the bassline:

G|------------------------------------------------------
D|------------------------------------------------------
A|-3-3--3-3--3-3--3-3-s-6-6-6--3-3--3-3-3-3-3-3-s-5-5-5-
E|------------------------------------------------------

G|-----------------------------------------------------------
D|-----------------------------------------------------------
A|-----------------------------------------------------------
E|-4-4--4-4--4-4--4-4-s-13-13-13--3-3--3-3--3-3--3-3-s-6-6-6-


Another riff that appears in the song comes after the bassline initially
plays two times, this riff is:

E|-8---------
B|---10------
G|------8----  This riff is also played when the drum track kicks out
D|--------10-  for un momento.
A|-----------
E|-----------


After that play a C5 chord.  The next riff is that almost -solo- type riff
but it~s not.  This is it:

E|--------------------------------------------------
B|----------4--3---------------------1-------6------
G|-------5-------3-3--------------1-------3---------
D|----5--------------3-----3p1--1-------3-----------
A|-3------------------------------------------------
E|-----------------------------------------------3--


Now, before Smith comes in with his vocals, that guitar line is (I am not
sure if I play it an octave higher but here it is):

E|-6~-----------6-6--4-4--3----4----1-
B|------------------------------------
G|------------------------------------
D|------------------------------------
A|------------------------------------
E|------------------------------------


After that a keyboard plays  E --6--4--3-, then Smith starts singing.
While he is singing, there is that freaky guitar line, played with delay,
that goes like:

E|-8--11--10--8--8--11--10--8-----11--10--8-----10--11--13-
B|-----------------------------9-------------8-------------
G|---------------------------------------------------------
D|---------------------------------------------------------
A|---------------------------------------------------------
E|---------------------------------------------------------
