Trampled Underfoot by Led Zeppelin

There are only a few guitar parts essential to the song.
There are also some fills played with a wah-wah, but theyre
not that hard to figure out(though they are to remember).
There are several guitars doubling various parts of the song
and some have a wah-wah on them.

Heres the main riff:

e---------------------------------------------------------------------------
b-2-3-----------------------------------------------------------------------
g-2-3--2-3-0-------0--------------------------------------------------------
d------------3-0-3----------------------------------------------------------
a---------------------------------------------------------------------------
E---------------------------------------------------------------------------

And this ascending part:

e------5-5-5-------7-7-7---------10-10-10----------12-12-12-----------------
b---------------------------------------------------------------------------
g--4/6---------6/8---------9/11--------------11/13--------------------------
d---------------------------------------------------------------------------
a---------------------------------------------------------------------------
E---------------------------------------------------------------------------

And after that this is played:

e--11--11-------------------------11-11-------------------------------------
b--11--12--11-12------------------11-12-11-12-------------------------------
g-----------------12-10----10-12--------------12-10----10-12\---------------
d-----------------------12--------------------------12----------------------
a---------------------------------------------------------------------------
E---------------------------------------------------------------------------

And the chord before the keyboard solo and at the end of the song:

e---------------------------------------------------------------------------
b---------------------------------------------------------------------------
g---7-----------------------------------------------------------------------
d---5-----------------------------------------------------------------------
a---------------------------------------------------------------------------
E---------------------------------------------------------------------------

Thats really about it except for the wah-wah bits here and there.
Enjoy,
CHUCK
