Okay, I'm just posting the main riffs of the song, you can easily figure where they go.
It starts with a Em chord, or if you prefer a E5. Then goes the main riff of Enter
which is this one:
|------------||------------||------------||------------||-----/7-----||-0-0----6-5-| p p
And here comes the riff of Taxman, transposed to E:
|------------||------------||------------||------------||---7-----5v-||-0---5h7----|
During the vocals, it's two times this riff, a guitar plays two E5 while the other one
two times the riff above and back to the start.
And the "chorus" is:
|------------|------------|------------|------------||------------|------------|------------|------------||---7-----5v-|---7-----5v-|------------|------------||-----5h7----|-----5h7----|---7-----5v-|------------||-5----------|-5----------|-----5h7----|---7-----5v-||------------|------------|-5----------|-0---5h7----|
There are no more riffs, listen to the song to figure what part goes where and that's all.
Have fun with Beatallica.
