In the very bottom of the tab you'll find "The Geek's Corner",
where we'll extend the chords to something a little more exotic
and add fills to spice things up - only for the hardcores/geeks.

Throughout the entire song Thom plays mainly a bass note and and high
melody notes that really fucks up the harmonies and gives that weird and
frustrating sound, which is very characteristic for Radiohead as well.
"Hail To The Thief" (recommended!) is a great example of this. If these
weird notes were to be added the chords, it'd really spice things up:

   [Ab] [C]   [Ab6] [C]        [Ab]   [Ab6]         [G]    [G7]         [Bb5]    [Bsus2]        [E5]    [E6]
|--4--->--1----|   |--4-->--4---|   |--3-->--3---|   |------>--1----|   |--0--|>--9---|
|--1--->--4----|   |--4-->--6---|   |--3-->--6---|   |------>--1----|   |--0--|>--9---|
|--1--->--1----|   |--5-->--5---|   |--4-->--4---|   |--3--->--3----|   |--4--|>--9---|
|--1--->--1----|   |--6-->--x---|   |--5-->--3---|   |--3--->--3----|   |--2--|>--6---|
|--3--->--3----|   |--6-->--6---|   |--5-->--5---|   |--1--->--1----|   |--2--|>--7---|
|------>-------|   |--4-->--4---|   |--3-->--3---|   |------>-------|   |--0--|>--0---|

   |---4----|   - 2nd finger (middle)
   |---6----|   - 4th finger (pinky)
   |---4----|   - 1st finger (index)
   |--------|
   |---5----|   - 3rd finger (ring)
   |---3----|   - thumb

...All these chords can be played instead of the regular chords from above.
You can also add these (and your own!) melody notes to the chords:

      [C]                   [Fm]
  |---0---0-1-3---|   |---1-----------|
  |---1-----------|   |---1---1-2-1---|
  |---0-----------|   |---1-----------|
  |---2-----------|   |---3-----------|
  |---3-----------|   |---3-----------|
  |---------------|   |---1-----------|

These notes are played in the verses and prechorus at some point, but just
add as many small melodies (these are very small) as possible as it gives
this extra momentum to the guitar that usually only play chords, go for it!
