This is another song in an "Alan Parson" mood, with an Andy McKee flavor.
Here's the tuning for this song: D G D G B D
Change Low E string to D
Change A string to G
Leave D string
Leave G string
Leave B string
Change High E string to D
The "X" mark in the tablature = Thumb
There are few spots that need to be worked carefully in order to play them correctly. I'll detail these parts in the next two sections of this tutorial.
The thumb playing bass is quite important as it gives the "groove" to the song because the rhythm is quite straight, so pay close attention to it.
