Ok so essentially it's just:

C, Em, F, G             (Sounds good along with the track if you arpeggiate the chords)

All the way through, but that probably won't be accepted so I will tab the intro as a 
piece rather than a vibraphone piece or whatever it is:

e----8----8-10-12----12-10-13----13-12-15----15-13-12---------------|
B-------------------------------------------------------------------|
G-------------------------------------------------------------------|
D-------------------------------------------------------------------|
A-------------------------------------------------------------------|
E-------------------------------------------------------------------|

Repeat, except last three notes.

And there you go really.
