Artist: Madonna
Song: X-Static Process
Tuning: Standart
Tonality: C Maj\A min
Notes: This song (instrumentally) is just an interpretation of I-IV-V chord 
progression arpeggios, but I set a level to intermediate 'cause I really doubt 
that novice could play it. Eventually, you can try by just strumming chords and 
sing along to the chords.
The whole songs plays with arpeggios, like this:
(r is rhythm, you sing it with you leg beat like metronome, it goes like one, two, 
three, four, one two three, four):
e|--------------------------|
b|---1----------1-----------|
g|---------2---------2------|
d|--------------------------|
a|---0----------------------|
e|--------------------------|
r|---I---II----III--IV------|
(well, that's not a mistake of tabbing, you really hit the string 'between' the 
steps, not on the beat actually)
So it goes:
--The main riff--
     Am (x02210@1)           C (x32010@1)            G (320003@1)              Am (x02210@1)e|----------------------------------------------------------------|
b|---1-----1--------1------1-------0------0---------1-------------|
g|-------2---2-----------0---0----------0---0---------------------|
d|----------------------------------------------------------------|
a|---0--------------3-------------------------------0-------------|
e|---------------------------------3------------------------------|

And for the chorus it's just the same but with a little variations, I believe that 
you can easily figure it out by yourself.
