There are 2 guitars used throughout this song. This is Guitar 2 - which takes more of a lead role. For Guitar 1 visit this ActionTab instead. Although it's a long song, most of the riffs are quite short and can be learned quickly. Much of the song's length is down to repeating the same riffs over and over.
Either guitar part is quite straightforward to learn and play, the main difficulty is building the speed. It is a fast song. Just do the usual - get it right at a slow speed first and then work at speeding up.
Riff 1 - Play this little repeating melodic riff. Meanwhile, Guitar 1 keeps playing the A5 powerchord.
Riff 2 - Both guitars play this short riff together, although this guitar plays single notes. The other guitar plays powerchords.
Riff 3 - This is a fast lick. Both guitars play it the same way. If it gives you problems, you can drop the low F# note and just play the higher F# instead. This still sounds ok, and is a lot easier because you don't have to skip strings quickly.
Riff 4 - Same for both guitars. Just bounce between the D major and A major chords. The chord changes are sometimes fast here, which may take some work to get the hang of, but nothing too drastic.
Riff 5 - This is a short descending lick played once in the song, before the chords from Riff 4 occurs the second time in the song.
Riff 6 - While Guitar 1 plays a little descending lick, this guitar plays these descending double stops before joining in on the end riff.
Riff 7 - This is the end riff for the song and both guitars play the same thing. It's very easy, just keep cycling through the same 3 powerchords until the end. Then finish the song by playing Riff 1 again for 1 last round.
