Standard Tuning - EADGBE

Main Riff - Sounds like there is quite a lot of distortion and bass in the guitar.

When the main riff sounds slightly different if you just turn the single notes into chords like this.
|----------------------------------------------------------------------------------------------------------|
|----------------------------------------------------------------------------------------------------------|
|---------------------------------------------------------------9-----------14--7---9----------------------|
|-12--9-11--7---9--5--7--4--4--5---16---17----12--9--11--7--9---7---12---9--12--9--11----------------------|

For the bit that goes “I don’t know why I feel so tongue tied” there isn’t any guitar really but I thought I’d tab out the notes he sings just so there is something to play when this part happens.

 Then it goes back in to the main riff again…

 The main riff may change a little later in the song but there’s too many things going on at once to be able to concentrate on the riff to notice such tiny changes. Then again it might be the same, just sounding different because of all the other parts of the song that come into it.
