"Defying Gravity" is the main musical score from the theatre show Wicked, though you may have also come across it in Glee.
It's a long song featuring monologues and complex duets, so I've pulled out the main verses and chorus so you can play the melody you know and love - happy practice!
D - C# D A D-C# .A
Something has changed within me
D - C# D .B .A .A
Something is not the same
D C# D A - D C# .A ^D
I'm through with playing by the rules
^C# A - D D-E E-D
Of someone else's game
G G F# D - .A .G - D
Too late for second guessing
G G G F# D B-F# A
Too late to go back to sleep
G G F# E D D-.A
It's time to trust my instincts,
G F# E-D E A
Close my eyes and leap
A A ^E ^D F#-A-D F#-E-E
It's time to try defying gravity
A A ^E ^D F#-A-^D F#-E-E
I think I'll try defying gravity
D G F# E D D
And you can't pull me down
A G F#-G-F# D-.A
I'm through accepting limits
D C#-D .B .A .A
'Cause somone says they're so.
D C# D A-D C# .A ^D
Some things I cannot change but 'till
^C# A B D-E E-D
I try, I'll never know
A G F# D .A-.G
Too long I've been afraid
D G-F# G F# D B A
Of losing love I guess I've lost
G G F# E
Well if that's love
D D .A G F# E D A
It comes at much too high a cost
A A-^E ^D F#-A-D F#-E-E
I'd sooner try defying gravity
A A ^E-^D
Kiss me goodbye
F# G-A-^D F#-E-E
I'm defying gravity
D G F# E D D
And you can't pull me down...
