Psycho by Muse

First off, you will need to tune your guitar to dropped “D” tuning so that low to high your guitar will be tuned to DADGBE.

The song starts with simple single string riff happening entirely on the low D string. Since the left hand notes are pretty simple it will give you a good opportunity to lock into the groove of the riff which is probably the most important thing to concentrate on.

You will also want to make sure you keep the slow bend well timed and in tune. 

This all leads into the chorus riff which is also performed mostly on the low D string. This chorus riff does require a bit of a stretch at one point so make sure you have your thumb in the proper position behind the neck in order to let your fingers reach those notes easily.

The verse of the song brings everything down to a much lower dynamic level and contains a simple rhythm throughout with a heavily muted feel to it. However, there are many fills thrown into this riff and it moves around the fretboard quite a lot. 

Its a great song to learn and really feels good when you get it.
