http://en.wikipedia.org/wiki/Atomic_Rooster You can play the main riff 2 ways; 1-On the E + A or 2-The harmony on the D + G. It like John Du Cann played it on the E then over dubbed the harmony (or visa versa). I usually it on the E (mainly because Cann uses vibrato on the string, not essential but if you to sound 'truer' tot the original) but on the last run through to give it a bit of I play the power chord. Main Riff (E + A) (I'll upload the intro later): E------------------------------------------¦ B------------------------------------------¦ G------------------------------------------¦ D------------------------------------------¦ A-----------3--5-----3---------------------¦ E---5---5----------------5--3--5---3-------¦ and on the D + A... E------------------------------------------¦ B------------------------------------------¦ G-----------5--7-----5---------------------¦ D---7---7----------------7--5--7---5-------¦ A------------------------------------------¦ E------------------------------------------¦ This next part is really easy too, its just a basic strumming technique which is easy to work out when you listen to the track, so I'll just put the notes/chords to play. As the 'main riff', the E + D are hamronised, but no vibrato is used here so you can play like a power chord but muting out the A: E------------------------------------------¦ B------------------------------------------¦ G------------------------------------------¦ D--7--6--5--4------------------------------¦ A--x--x--x--x------------------------------¦ E--5--4--3--2------------------------------¦ I'll upload the rest of the song later :)
