Here is the TAB for Lucy in the Sky with Diamonds. This is just the very beginning, but it is the hardest part. The rest is just chord stumming.

In case you are unfamiliar with how to read TAB see my tutorial here --> READING TAB

Also seeing is everything ...so here is a video of me playing this so you can see what it looks like --> VIDEO

I've marked arrows in the first mesure that show you where to change hand positions.

Please note that the mesure marked "sing" must be played before "ending 2" as well even though it is not noted above becuase of the constraints of space

 

(play this part with riff)

Picture yourself in a boat on a river

With tangerine trees and marmalade skies

Somebody calls you, you answer quite slowly

A girl with caleidoscope eyes

  
   Bb                    C                  
Cellophane flowers of yellow and green
 F                  Bb  
Towering over your head
C                          G               D7  Em7   D       
Look for the girl with the sun in her eyes and she's gone    
CHORUS:
   G           C          D        
Lucy in the sky with diamonds
   G           C          D         
Lucy in the sky with diamonds
   G           C          D       D  A         
Lucy in the sky with diamonds, ahhhhh
