An organistion named R4DI0H34D has developed an new encryption system codenamed G.

Previous encryption methods include V0C4l5 created by encryptor codenamed Y0RK3.

Here is some encrypted text we found, can you crack the cipher?


It may be easier to see in text:


What does the text say?

(Not part of the puzzle)

I have tried to make this cipher as original as I can, so have fun and good luck!

Hint 1 (from comments):

You don't need to know about Radiohead songs to solve this puzzle - not the song notes or anything, It's mostly a theme, so you can solve it without knowledge of Radiohead.

I think the answer is:

AIRBAG - A song from Radiohead's album "OK Computer" enter image description here

Here's how I got that answer:

The letters are the strings on a standard-tuned 6-string guitar, and the numbers are frets on those strings. If you map out these frets on chord charts, they make upside-down, capital letters. The R actually looks like a P, but I'm pretty sure it's Airbag since that's the title of a Radiohead song.

Step 1:

Draw the shapes in reverse order, so that when you flip it, it makes sense.

Step 2:

Flip it and connect the dots.

  • $\begingroup$ Ah, you got me... and I was so close... I just couldn't read the letters properly... I was getting "AIP8A_"... the last symbol made no sense to me no matter what way I turned it. $\endgroup$ Feb 2 '17 at 9:02

All the hints are simple l33t code.
This is about the music band Radio Head, the previous encryption method was vocals and the encryptor was Yorke(the lead signer.)
This is probably the lyrics of one of their songs. But I have yet to confirm.
Codename G might mean that the new encryption method is guitar and the letters A to G could be the guitar chords. The numbers under might be the number of repetitions before going to the next chord.
I suspect that e = Em(e minor)

  • $\begingroup$ @Melkor except that I can't play guitar and pretty much know no songs of radiohead. Unless I read the chord sheets of all their songs until I find it, it might be impossible for me. I guess the best way would be to just play the chords and recognize the song. $\endgroup$ Feb 1 '17 at 7:52
  • $\begingroup$ Not exactly. No spoilers but I tried to make it so anyone can solve who has a very basic knowledge of the guitar. $\endgroup$

    $\begingroup$ I'm guessing those letters refer to the strings on a guitar in standard tuning. EADGBe. $\endgroup$
