I think that this is how you play this song in the correct key, The chords are the
same all the way through :)
F# C#
I believe in nothing
D#m B
Not the end and not the start
F# C#
I believe in nothing
D#m G# A#
Not the Earth and not the stars
I believe in nothing
Not the day and not the dark
I believe in nothing
But the beating of our hearts
I believe in nothing
One hundred suns until we part
I believe in nothing
Not in sin and not in God
[ Tab from: https://www.guitartabs.cc/tabs/0-9/30_seconds_to_mars/100_suns_crd_ver_3.html ]
I believe in nothing
Not in peace and not in war
I believe in nothing
But the truth and who we are.
Alternately, you could play it with a capo on first fret:
F C
I believe in nothing
Dm Bb
Not the end and not the start
F C
I believe in nothing
Dm G A
Not the Earth and not the stars
I believe in nothing
Not the day and not the dark
I believe in nothing
But the beating of our hearts
I believe in nothing
One hundred suns until we part
I believe in nothing
Not in sin and not in God
I believe in nothing
Not in peace and not in war
I believe in nothing
But the truth and who we are.
I hope that this is helpful :)
