Hallelujah by Leonard Cohen - fingerstyle guitar sheet music in pdf format.
 
You can watch the arrangement here:
- Solo guitar: https://www.youtube.com/watch?v=XTxPXDT83pc
- Guitar and vocal: https://www.youtube.com/watch?v=6qpuxUZcO90
 
Provided in two forms: sheet music and sheet music + tabs (in a zip archive).
 
The first half of the arrangement is easy and the second one is more complex - you can skip the second half and play just the first half only if you like.
 
Enjoy!
