This is the main guitar for the song called Tribute, buy Tenacious D. It can be played through on an acoustic guitar, or clean sounding electric. At certain points a distorted guitar joins in to rock things up a bit. There is also a more atmospheric electric lead guitar playing fills. We'll look at those frilly parts in separate ActionTabs. Here are all the main song parts:

Main Riff - This verse riff is short and sweet. It repeats a LOT in the song. It's just an A minor chord played with hammer ons thrown in.

Palm Muted Riff - Short, nice and easy.

Pre-Chorus - Some standard chord changes here, nothing fancy but sounds good. Here's the progression:

A minor - G major - F major (repeat)

Chorus - More straightforward chords:

D major - F major - C major - G major - F major

Repeat those chords once, and on the last F major do this.

That's all the main song parts, but there are also the following diversions:

Chorus 2 - After the gap where Jack Black shouts 'Rock!'. These are the same chords as first time, but with a distorted rock guitar in the background and slightly different emphasis on the strums.

Bridge - After that chorus, the main A minor verse riff changes a little to include a G major chord. Then the song takes this twist:

A sus2 - G6 add9 - D major - F sus2 - A sus2 (repeat)

There is a gap in the middle of this part while they sing silly noises for a bit.

Ending - The song ends on a kind of spanish progression:

E major - F major - G major (repeat, sometimes with muting to break up the rhythm)

Then go bonkers on the F major and finish with this.
