Phil Lovett the friendly proxy's seven step guide to Playing the first bar or so of 'the load'.

Right, guitar lesson time. This is gonna be pretty bad, as guides go, but hopefully you'll be able to work things out yourself using this guide as a framework.

The tuning for this is standard, EADGBe, and the first thing to do is find the fourth position (that is, when your index finger is at the fourth fret). You should put your index finger on the fourth fret of the G string, and your middle finger on the fifth fret of the B string. On a guitar tab (where the row shows the sting, and the number shows the fret) it should look like so;

E||---
B||-5-
G||-4-
D||---
A||---
E||---

Not terribly difficult, eh? The next step is what gives that fluency to the intro. After strumming the B and G strings (I pluck using my index and middle finger, but it's really whatever method you're comfortable with as far as I know) you need to hammer on to the sixth fret of the B string using your third finger, so the sound is changed without strumming the string again. Now the tab looks more like this;

E||----
B||-5--
G||-4h6
D||----
A||----
E||----

Then, without changing the position, just strum your B and E strings.

E||----0
B||-5--5
G||-4h5-
D||-----
A||-----
E||-----

Now it gets a wee bit more complex. You'll need to barre the fifth fret in the E and B string, that is, hold down both strings with one finger, then hammer on to the seventh fret on the B string. This might be marked out on your guitar's fretboard. Afterwards, play the E sting again, without changing the position.


E||----0-5--5
B||-5--5-5h7-
G||-4h5------
D||----------
A||----------
E||----------

Now you go back to the position you first played, and pluck that, except hammering onto the seventh fret of the B string rather than the sixth fret of the G string, comme ca;


E||----0-5--5----
B||-5--5-5h7--5h7
G||-4h5-------4--
D||--------------
A||--------------
E||--------------

Then play the 5 4 position again, twice, the second time hammering to the sixth fret on the G string, same as before (note: I almost missed the second repeat of the chord, thank you to Taylor for tabbing this out far better than I did);

E||----0-5--5----------
B||-5--5-5h7--5h7-5-5--
G||-4h5-------4---4-4h6
D||--------------------
A||--------------------
E||--------------------

Now play the 5 4 position again, before sliding down, while holding the position, so that you're playing the third fret on the B string and the second fret on the G string. Hammer on to the fourth fret on the G string (this position is the same as the original, just transposed downwards). Repeat this twice, missing the hammer on on the final repeat, like so;

E||----0-5--5----------------------
B||-5--5-5h7--5h7-5-5---5-3---3---3
G||-4h5-------4---4-4h6-4-2h4-2h4-2
D||--------------------------------
A||--------------------------------
E||--------------------------------

You're coming to the end of the intro now. Wait a few beats, then play the second fret on the G and D strings, hammering onto the fourth fret of the D string. I find the best way to do this is to play the second frets on the G and D with the middle and index fingers, respectively, as opposed to using a barre, then hammer on with your pinky. The tab now looks like this;


E||----0-5--5-----------------------------
B||-5--5-5h7--5h7-5-5---5-3---3---3-------
G||-4h5-------4---4-4h6-4-2h4-2h4-2----2--
D||------------------------------------2h4
A||---------------------------------------
E||---------------------------------------

Hold the position, and pluck the G and D strings, consecutively in that order;

E||----0-5--5--------------------------------
B||-5--5-5h7--5h7-5-5---5-3---3---3----------
G||-4h5-------4---4-4h6-4-2h4-2h4-2----2---2-
D||------------------------------------2h4--4
A||------------------------------------------
E||------------------------------------------

The final chord is a simple barre over the second fret of the strings from E to D. If necessary, mute the E string by touching it (but not holding a fret down) with one of your free fingers. Strum downwards from the A string. The final Tab looks like this;

E||----0-5--5----------------------------------||
B||-5--5-5h7--5h7-5-5---5-3---3---3-----------2||
G||-4h5-------4---4-4h6-4-2h4-2h4-2----2---2--2||
D||------------------------------------2h4--4-2||
A||-------------------------------------------0||
E||--------------------------------------------||

With practice, hopefully that'll sound right good. Best of luck to you, and sorry to Veigar and everyone else in the safehouse, who had to put up with me going over the intro over and over again.

*EDIT*  You may need to use a larger screen to read the tab, on smaller things like smartphones it wraps around. Fixed font changing partway through.
